Fix bug in persist events when dealing with non member types. (#7548)

`_is_server_still_joined` will throw if it is given state updates with non-user ID state keys with local user leaves. This is actually rarely a problem since local leaves almost always get persisted by themselves.

(I discovered this on a branch that was otherwise broken, so I haven't seen this in the wild)
