rabbit_stream_manager: Handle internal_error in stream declaration

`rabbit_stream_queue:declare/2` may fail to declare if the metadata
store operation(s) time out, like when the cluster has a minority of
online nodes. This would cause a case_clause error in
`rabbit_stream_manager:do_create_stream/4`. We can print a warning
log and return `{error, internal_error}` instead.
