tests: filter out uninteresting log events
Core has new ui.log() calls added (for tracking extension loading and
performance, for example), but in test-discovery-obshashrange.t it produces a
bunch of lines that are unrelated to the test. So we filter them out to not
touch test output. This is inspired by 1de3364320af in core.
