Check unique constraint errors when manually inserting migrations (#2712)
This should avoid unnecessary logging on startup if the migration (were
we need `InsertMigration`) was already executed.
This now checks for "unique constraint errors" for SQLite and Postgres
and fails the startup process if the migration couldn't be manually
inserted for some other reason.

Change detection of already executed migrations (#2665)
This changes the detection of already executed migrations for the
roomserver state block and keychange refactor. It now uses schema tables
provided by the database engine to check if the column was already
removed. We now also store the migration in the migrations table.

This should stop e.g. Postgres from logging errors like `ERROR: column
"event_nid" does not exist at character 8`.

Detect types.MissingStateError in CheckServerAllowedToSeeEvent (#2667)

State handling tweaks (#2652)
This tweaks how rejected events are handled in room state and also to not apply checks we can't complete to outliers.

* Fix flakey sytest 'Local device key changes get to remote servers'

* Linting

* Add regression test

* Unbreak tests

* ALL THE LOGS

* Fix a race condition which could cause events to not be sent to servers

If a new room event which rewrites state arrives, we remove all joined hosts
then re-calculate them. This wasn't done in a transaction so for a brief period
we would have no joined hosts. During this interim, key change events which arrive
would not be sent to destination servers. This would sporadically fail on sytest.

* Unbreak new tests

Remove error when state keys are missing for user NIDs (#2213)
* Remove error when state keys are missing for user NIDs

There is still an actual bug here somewhere in the membership updater, but this check does more harm than good, since it means that the key consumers don't actually distribute updates to *anyone*. It's better just to deal with this silently for now.

To find these broken rows:

```
SELECT * FROM roomserver_membership AS m WHERE NOT EXISTS (
	SELECT event_state_key_nid FROM roomserver_event_state_keys AS s
	WHERE m.sender_nid = s.event_state_key_nid
);
```
