Subject DO NOT REPLY [Bug 50860] In case of invalid or empty slqQuery connection are always invalidated without usefull information

Although it seems similar to Bug 50660, the case of a `null` query is really a
misconfiguration error.

I think it should be treated differently from "invalid" SQL case and in case of
`null` query throw RuntimeException that tells the user about misconfiguration.

I also think that obvious configuration validation (validationQuery is null or
empty, when validation is enabled ) has to happen when the connection is
initialized (or better yet in ConnectionPool.init), because in my test it would
not happen before the validationInterval would have expired, and a one-off
message in the middle of log stream does not call to much attention.
