Most tests do not need to use custom collection and database names. For those that do, they should ensure the database is cleaned up after test execution (e.g. similar to how BaseTest drops collections in the doctrine_odm_tests DB).
Use default database for MODM140Test
Custom databases do not get cleaned up by BaseTest (see #351).
Only "doctrine_odm_tests" database is left after running test suite which is good ticket wise
Closing since it's no longer an issue
