This will solve the issue of naming the durable per server for
the "retained messages" stream in situation where a cluster
of servers would not have JetStream defined but connect to another
cluster that has it. All the servers within the cluster without
JetStream would cause the durable's delivery subject to be updated
to the last server starting the durable.
Updated the check for mqtt requiring JetStream if running in
standalone mode to check that no leafnode configuration is present.
Replaced use of fmt.Errorf() when the string was static with
errors created with errors.New(). Updated tests that were checking
for errors to use those errors instead of repeating the string.
Added test that has a hub cluster with JS enabled and a remote server
that has mqtt{} without JetStream and ensure that this works.
