Only use test-error-query in snapshot builds

Fixes #130978

You'll want to add the test-release label to actually test this in release builds. We don't run those tests by default on pull requests.

Thanks for following up on this @smalyshev !

LGTM

I find it somewhat confusing that the tests pass w/o the plugin installed. I guess they are disabled in non-snapshot builds elsewhere?

[smalyshev]

@mark-vieira yes, they should be disabled by either individual or class-level assumeTrues if they need snapshot functionality.
