Update getting pushrules, add tests, tweak pushrules (#2705)

This PR
- adds tests for `evaluatePushrules`
- removes the need for the UserAPI on the `OutputStreamEventConsumer`
(for easier testing)
- adds a method to get the pushrules from the database
- adds a new default pushrule for `m.reaction` events (and some other
tweaks)
