Update for SQLAlchemy 2.0.0

The SQLAlchemy 2.0.0 has some changes that caused your tests to fail. I fixed
the nested transaction and the select clause.

Removed one test case, because it now causes StopIteration in mock library.
Basically it tries to call mocked method in rollback and it is stuck in endless
loop.
