Sytest was using a wrong `history_visibility` for `invited`
(https://github.com/matrix-org/sytest/pull/1303), so `invited` was
passing for the wrong reason (-> defaulted to `shared`, as `invite`
wasn't understood).
This change now handles missing events like Synapse, if a server isn't
allowed to see the event, it gets a redacted version of it, making the
`get_missing_events` tests pass.
This should hopefully fix an entire class of problems where components
downstream from the roomserver (i.e. the sync API) could just lose a
whole bunch of state after a rewrite operation like a federated join.
The root of the bug is that we set `RewritesState` in the output event
which instructs downstream components to purge their copy of any room
state, but then didn't send the entire state snapshot in
`adds_state_event_ids` so the downstream state ends up being incomplete
as a result.
Previously `LoadMembershipAtEvent` would fail if the state before one of
the events was not known, i.e. because it was an outlier. This modifies
it so that it gracefully handles not knowing the state and returns no
memberships instead, so that history visibility doesn't freak out and
kill `/sync` requests dead.

Don't store soft-failed events as rejected
This should hopefully deflake Backfill works correctly with history visibility set to joined as we were using the default shared visibility, even if the events are set to joined (or something else)
