Richard van der Hoff bbb75ff6ee Exclude rejected state events when calculating state at backwards extrems (#6527 )

This fixes a weird bug where, if you were determined enough, you could end up with a rejected event forming part of the state at a backwards-extremity. Authing that backwards extrem would then lead to us trying to pull the rejected event from the db (with allow_rejected=False), which would fail with a 404.
