        https://bugs.webkit.org/show_bug.cgi?id=32056

        * Scripts/modules/bugzilla.py:
         - Fix _parse_attachment_ids_request_query to return ints instead of strings.
        * Scripts/modules/commands/download.py: Remove unneeded imports.
        * Scripts/modules/commands/queries.py: Ditto.
        * Scripts/modules/commands/queues.py: Ditto.
        * Scripts/modules/commands/upload.py: Ditto.
        * Scripts/modules/scm_unittest.py:
         - Fix to expect the \n after the path since echo adds an \n.
