Ignore ephemeral classes in test_all_present()

Fixed a regression in the test suite where the test called
``CompareAndCopyTest::test_all_present`` would fail on some platforms due
to additional testing artifacts being detected. Pull request courtesy Nils
Philippsen.

In some circumstances, ephemeral class objects that are created within
the scope of a test method don't seem to be garbage collected directly
on exit. Filter out classes created in test modules.

Fixes: #7450
Closes: #7451
