We should just let the `auth` object null and dont send it at the
first try and wait for the servers response. This worked in the past
but now it is broken because of changes in the
matrix_api_lite. This could also be fault for some
bootstrap issues.
I have also removed an unnecessary check if a String is a String and just made it a
null check because this was intended at this point.
Because of that this blocks uiaRequests it is a hotfix and therefore directly bumps the version.
