[issue40690] unittest: if FunctionTestCase is imported, the loader loads "tests" from it

Vitalii  added the comment:

If you make an import in a module with your tests

>From unittest import FunctionTestCase

then you will have 1 extra test in that module (the imported one), moreover, 
that test will be broken.
