[FLINK-8063][QS] QS client does not retry when an UnknownKvStateLocation.
## What is the purpose of the change
Fix bug in QS client. Before if the client submitted a query with invalid
queryable state name, it would retry the query indefinitely. This change fixes
it.
## Brief change log
The change is in the `KvStateClientProxyHandler` where we change the
conditions based on which we automatically retry a query.
## Verifying this change
Adds test `AbstractQueryableStateTestBase.testWrongQueryableStateName()`.
