This PR fixes issue #813 where appservice users were not being created, preventing appservices from functioning correctly:

  • Creates the appservice user (sender_localpart) during initial registration
  • Also creates users during authentication to handle existing appservices registered before this fix

The issue was that when an appservice registered, the corresponding user account for the sender_localpart was never created, which prevented:

  • Direct messages to the appservice bot user
  • The appservice from properly acting as its designated user

The fix should ensure that missing user accounts are created both:

  1. During initial appservice registration (for new appservices)
  2. During authentication (for existing appservices, so fixing them automatically)

Fixes #813 where appservice users were not being created when the
appservice was registered, causing bridges like mautrix-telegram
to fail on startup.

The fix creates the appservice's sender_localpart user if it doesn't
already exist during the registration process, matching the expected
Matrix appservice behaviour.

Ensures appservice users are created during authentication requests,
fixing the issue for appservices registered before the initial fix.
This allows existing appservices to work without re-registration.

This would create for any user in the regex, not sure we need to do that - I think the issue was the account in sender_localpart? Ignore me if I'm wrong here

If it is what needs to happen, then it should only happen for exclusive namespaces to stop, e.g. doublepuppetting from accidentally creating accounts.
