If the `no_auth_user` is set in the `websocket{}` block and a
server creates a leafnode connection using the websocket port,
and does not provide credentials, that no_auth_user should be
used, but was not.

When a block's subject meta state was swapped out and subsequently loaded back in with only one subject present, but other messages with different subjects were added later, a filtered get could return the wrong result.

A request to `$SYS.REQ.SERVER.PING.JSZ` would now return something
like this:
```
...
"meta_cluster": {
"name": "local",
"leader": "A",
"peer": "NUmM6cRx",
"replicas": [
{
"name": "B",
"current": true,
"active": 690369000,
"peer": "b2oh2L6w"
},
{
"name": "Server name unknown at this time (peerID: jZ6RvVRH)",
"current": false,
"offline": true,
"active": 0,
"peer": "jZ6RvVRH"
}
],
"cluster_size": 3
}
```
Note the "peer" field following the "leader" field that contains
the server name. The new field is the node ID, which is a hash of
the server name.

This was discovered by new test TestJetStreamClusterRemovePeerByID.
I saw this on Travis and repeating the test locally with -count=10
I was able to reproduce. The issue is cc.meta being nil but accessing
cc.meta.ID() directly.

If the client pull requests has a max_bytes value and the server
cannot deliver a single message (because size is too big), it
is sending a 409 to signal that to the client library. However,
if it sends at least a message then it would close the request
without notifying the client with a 409, which would cause the
client library to have to wait for its expiration/timeout.

Since the second batch was already past the 5min mark and a bit
longer than the first batch, it is a good opportunity to add
this new test in a new file. Updated runTestsOnTravis and travis.yml
accordingly.

The CLI will now be able to display the peer IDs in MetaGroupInfo
if it choses to do so, and possibly help user select the peer ID
from a list with a new command to remove by peer ID instead of
by server name.

This can be helpful after a partial cluster restart since in that
case the server name may not be known. However "server report jetstream"
would report the peer ID that then can be used.
For instance here is the output after a cluster restart where server "C"
is not restarted.
```
nats -s nats://sys:pwd@localhost:4222 server report jetstream

With a change to the NATS CLI we could have something like:
```
nats -s nats://sys:pwd@localhost:4222 server raft peer-remove jZ6RvVRH --by_id

* changed format of JSClusterNoPeers error
This error was introduced in #3342 and reveals to much information
This change gets rid of cluster names and peer counts.
All other counts where changed to booleans,
which are only included in the output when the filter was hit.
In addition, the set of not matching tags is included.
Furthermore, the static error description in server/errors.json
is moved into selectPeerError
sample errors:
1) no suitable peers for placement, tags not matched ['cloud:GCP', 'country:US']"
2) no suitable peers for placement, insufficient storage

Code change:
- Do not start the processMirrorMsgs and processSourceMsgs go routine
if the server has been detected to be shutdown. This would otherwise
leave some go routine running at the end of some tests.
- Pass the fch and qch to the consumerFileStore's flushLoop otherwise
in some tests this routine could be left running.
Tests changes:
- Added missing defer NATS connection close
- Added missing defer server shutdown
