All integration tests seems to work fine. Almost fine.
Each test one-by-one and all tests together show green light.
Fixed PagingPerformanceTests tests. Fixed my previous fix, so database now is recreated at the beginning of test fixture and after test. This excludes a problem with index growing automatically hence a little bit roughly.
Continue fixing unit tests
All unit tests are green now.

One more thing about integration tests: when running PagingPerformanceTests test, don't forget to close everything that may use connection to the database, because it will be recreated.
