logcat: test: inject for *.event_tag_filter 

Inject a message for event_tag_filter and bucket tests. The former
registered an occasional failure.

Switch order of EXPECT checks so that constant is on the right so
that error reports make more sense.

Test: gTest logcat-unit-tests --gtest_filter=*.event_tag_filter
Test: gTest logcat-unit-tests
