* Test whether an event not in a room's timeline causes notification count increase
Commited separately to demonstrate test failing before.
* Don't fix up notification counts if event isn't in the room
As explained by the comment, hopefully.
* Fix other test
* Ensure we don't overinflate the total notification count
By correctly comparing push rules before & after decryption
* DRY the code
* Testsssss
* Update tests
* Validate vars early
* Split out unread counts for total and highlight to different logic blocks
* Add tests for ignoring non notifying events
* Fix possibly incorrect tests?
* lint fix
* Refactor currentTotalCount
* Track Total locally too
* Lots of total count assumptions and comments
* Adjust for threading too
* Fixup tests
* a word
* lint fix
