remove hardcoded SQL queries in tests

[Matthieu Huin]

There are several occurrences of hardcoded SQL queries at least in test_sql_upgrade.py:

* https://github.com/openstack/keystone/blob/master/keystone/tests/test_sql_upgrade.py#L941
* https://github.com/openstack/keystone/blob/master/keystone/tests/test_sql_upgrade.py#L946

Due to variations in databases these queries might not work all the time, and should be replaced by queries built with sqlalchemy.

A code sweep is in order to find and replace any hardcoded queries.
