[RecentChangeTest] Refactor unit test to test better test the issue
* assert used message-keys/variables instead of hardcoded values
* Pass $comment to the assertion helper instead of using it by default so that actions that don't use a comment (such as patrol) don't get forced a comment, to better replicate the IRC behavior
* Adding placeholder for Auto-Edit-Summary things that should also be checked in here, not sure how to do those yet
* Adding tests for block/* and protect/*
