CodeChecker does not warn when a clang-diagnostic checker is mistyped.

CodeChecker does not warn clang-diagnostic checker is mistyped. The issue can be reproduced with CodeChecker master. CodeChecker check --analyzers clang-tidy -l compile-commands.json -e clang-diagnostic-vlaa -o ./reports The above command should fail with an error that clang-diagnostic-vlaa checker is non-existing.

@vodorok This should be rechecked with 6.24.0. I believe we did some works with regards to this...
