Fix flaky PION_LOG_*, more tests

[joeturki]

Description

I was tracking an issue with video feedback when I noticed the logs were flaky. Initially, I thought it was a bug, but I later discovered that PION_LOG_*=all is unreliable due to how the range map is ordered.

Added tests to cover everything.
