Small cleanup PR.
* Removed the unused `is_guest` argument
* Added a safeguard to a (currently) impossible code path, fixing static checking at the same time.

Bugfixes
--------
- Fix a bug introduced in v1.19.0 where appservices with ratelimiting disabled would still be ratelimited when joining rooms. ([\#8139](https://github.com/matrix-org/synapse/issues/8139))
- Fix a bug introduced in v1.19.0 that would cause e.g. profile updates to fail due to incorrect application of rate limits on join requests. ([\#8153](https://github.com/matrix-org/synapse/issues/8153))

The function is used for two purposes: 1) for subscribers of streams to
get a token they can use to get further updates with, and 2) for
replication to track position of the writers of the stream.
For streams with a single writer the two scenarios produce the same
result, however the situation becomes complicated for streams with
multiple writers. The current `MultiWriterIdGenerator` does not
correctly handle the first case (which is not an issue as its only used
for the `caches` stream which nothing subscribes to outside of
replication).
`StatsHandler` handles updates to the `current_state_delta_stream`, and updates room stats such as the amount of state events, joined users, etc.
However, it counts every new join membership as a new user entering a room (and that user being in another room), whereas it's possible for a user's membership status to go from join -> join, for instance when they change their per-room profile information.
This PR adds a check for join->join membership transitions, and bails out early, as none of the further checks are necessary at that point.
Due to this bug, membership stats in many rooms have ended up being wildly larger than their true values. I am not sure if we also want to include a migration step which recalculates these statistics (possibly using the `_populate_stats_process_rooms` bg update).
Bug introduced in the initial implementation https://github.com/matrix-org/synapse/pull/4338.
