* Have replication clients remove _INT_STREAM_POS
Suppose worker A makes an internal http request from worker B. B may
make changes that A later learns about over replication. We want A's
request to block until it has seen those changes—mainly to ensure A's
caches are invalidated promptly. This helps provide read-after-write
consistency, eliminating entire categories of races and test flakes.
To implement this, B includes a top-level field `_INT_STREAM_POS` in its
response JSON. Roughly speaking, the field's value tells A what to wait
for. But we weren't removing that internal field before A's request
completed!
Introduced in https://github.com/matrix-org/synapse/pull/14820.
Fixes#15308.
* Changelog
When a room is deleted in Synapse we remove the event forward
extremities in the room, so if (say a bot) tries to send a message into
the room we error out due to not being able to calculate prev events for
the new event *before* we check if the sender is in the room.
Fixes#8094
With Redis commands do not need to be re-issued by the main
process (they fan-out to all processes at once) and thus it is no
longer necessary to worry about them reflecting recursively forever.

* Simplify by removing Optionality of `event_id`
* Replace names and avatars with None if they're set to dodgy things
I think this makes more sense anyway.
* Move schema delta to 74 (I missed the boat?)
* Turns out these can be None after all

It is not necessary to reach out to the database to check some
parameters if the auto-join rooms are not configured, or (in some cases)
if auto-create rooms is not configured.
