Subject: [PATCH] bpo-45400: Fix
 test_name_error_suggestions_do_not_trigger_for_too_many_locals on a1 releases

When test_name_error_suggestions_do_not_trigger_for_too_many_locals
run from a directory that contained "a1" somewhere in the path,
which was likely to happen when building from unpacked sources of a first
alpha release, it failed, as it asserts the string "a1" is nowhere in the traceback.

Now, we replace the full path in the traceback with basename to prevent this.
