[test] Avoid assertCountEqual in unittest_syncschema.py
It's not clear why this happens, but it seems that assertCountEqual does
strange things with unittest2 on Python 2 for equality comparison (trying to
sort constraint objects, even though BaseConstraint raise NotImplemented in
__lt__ from Yams 0.43).
So just avoid using it to get this test passing.
