Handle comment reaction upserted and removed for Feed

[gpunto]

Goal

Part of AND-796

Continuing to add missing event handling (and refactoring handler tests to parameterized tests). This PR adds handling of comment reaction events for Feed.

Implementation

The logic to change comment reactions is basically the same as the one for activity reactions implemented in #97

Testing

Not trivial to test manually in the sample because the comment reactions we're displaying don't come from a Feed instance, but from Activity. What one would need to do, for example, is adding code to observe and log comment reactions in an activity from Feed.state, then change comment reactions (even from the UI), and check that the emitted new comment reactions are correct.
