Tests: Suppress logging and warnings from temporary profile fixture

[sphuber]

When the test suite is run without specifying a particular test profile, one is created on the fly using the TemporaryProfileManager. This would create a temporary configuration directory and a temporary profile which would generate a UserWarning and some REPORT level log messages.

This info causes unnecessary noise and the warning even causes pytest to record that the tests issued a warning, but the warning is completely to be expected and benign, so here we capture the warnings and log messages.

Thanks! The implementation looks all good.
I just wonder, does this also suppresses the warning of deprecation message from aiida-core itself or the dependent packages, which we may expect from the pytest?

Not sure what you mean. This suppresses the warning and the logging no matter how this code is invoked. But in this case I think that is warranted, because these warnings and messages are not useful when setting up an automatic temporary profile.

I mean if there is some part of the aiida-core code using old deprecated APIs, or the deprecated APIs of other dependent packages, the pytest will find it and report. This PR basically suppresses all warnings, so pytest can not be the source for those warnings.

The messages being suppressed here are not deprecation warnings.

There are two things being suppressed:

• a UserWarning that is emitted when the .aiida folder is created. Normally this is when you launch AiiDA for the very first time. In this case, it is done by the TemporaryProfileManager because it creates a completely separate AiiDA config folder from scratch. Since that is the intended behavior, we don't need to see the warning each time, so I suppress it here.
• The TemporaryProfileManager creates a temp profile from scratch, including the temp Postgres database, and then migrates it. This results in a REPORT log message saying it is installing the base database schema. Again, this is not useful to have printed everytime when running the tests with the autogenerated test profile, so I suppress it.

Thanks for explanation @sphuber. It makes all sense. Cheers!
