[issue29912] Overlapping tests between list_tests and seq_tests

[Jim Fasarakis-Hilliard]

New submission from Jim Fasarakis-Hilliard:

Seems the CommonTests class defined in list_tests duplicates the testing performed by seq_tests.CommonTests in the following functions:

    test_index, test_count

Additionally, a part of test_imul from list_tests.CommonTests can be moved to seq_tests.CommonTests. (specifically, up until `        self.assertEqual(u, self.type2test([]))`).

Am I missing some non-obvious thing here or can I safely remove the two test functions in list_tests.CommonTests and move (while also adding a super call) part of test_imul from list_tests.CommonTests to test_imul in seq_tests.CommonTests?
