A couple instances of assertNoLogs were recently added to the codebase

which did not have an explicit logger argument. Python 3.10 has this

method in the standard library, but on 3.8 and 3.9 we get Django's

version, which differs very slightly from the stdlib one in that it does

not specify a None default for the logger argument. This caused tests

to break on those Python versions.

Ran unit tests.
