SOLR-14245: Fix ReplicaListTransformerTest
Previous changes to this issue 'fixed' the way the test was creating mock
Replica instances,
to ensure all properties were specified -- but these changes tickled a bug in
the existing test
scaffolding that caused it's "expecations" to be based on a regex check against
only the base "url"
even though the test logic itself looked at the entire "core url"
The result is that there were reproducible failures if/when the randomly
generated regex matched
".*1.*" because the existing test logic did not expect that to match the url or
a Replica with
a core name of "core1" because it only considered the base url

> Replica / ReplicaInfo should be immutable and their fields should be
> validated on creation.
> Some users reported that very rarely during a failed collection CREATE or
> DELETE, or when the Overseer task queue becomes corrupted, Solr may write to
> ZK incomplete replica infos (eg. node_name = null).
> This problem is difficult to reproduce but we should add safeguards anyway to
> prevent writing such corrupted replica info to ZK.
