Also sync other consumers when taking over as leader but no need to process snapshots when we are in fact the leader.

We were snappshotting more then needed, so double check that we should be doing this at the stream and consumer level.
At the raft level, we should have always been compacting the WAL to last+1, so made that consistent. Also fixed bug that would not skip last if more items behind the snapshot.

When a server was restarted and expired messages, but the leader had a snapshot that
still had the old messages we would reset complete follower stream state, this fix
just skips over the expired as we prepare the request to the leader.

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
```
