Improve tests

Browse source 
- Check callability of function.expect.with(...)
- Check serialization of MOCK_CONSTRAINT
- Actually test some variations of MOCK_CONSTRAINT usages
- Add more test for unique_ptr (move-only class)
- Remove redundant stuff from test_log and change a few values to catch mistakes
- Add test for *-matcher serialization
