Analogous to #37017, we should make sync `logout()` clear `request.auser`
if present. If `auser` is not present, I doubt `login()` should set it,
but if it is present, it probably should be set as well.

I personally think auser may need to be set as using `sync_to_async`
should still be valid and perhaps third-party code may have sync only code
assuming things will work using `sync_to_async`. I understand in your own
project you should use `alogin` instead
