[BUG] Exceptions shown in stderr when running PARQUET_TESTS

[davidwendt]

Running PARQUET_TESTS shows several errors and warnings to stderr. It is unclear if they are expected or not so if it is possible to suppress them when expected, it would make it easier to discern it them from actual errors.

Looks like we have an EXPECT_THROW()in all tests throwing an error above. We can look into suppressing them

[davidwendt]

I believe @vuule mentioned just suppressing the log output somehow.

[vuule]

The first idea that comes to mind is to RAII the logging away in the tests we know are meant to run into invalid/semi-valid cases.
We can discuss whether tests that don't expect warnings/errors should fail if there are any such messages in the log.
