Resetting the content_model and slot_role tables between test runs
requires the corresponding NameTabelStore instances to be reset
as well. We may however have many of them, buried in various services.
There is no easy way to reset them consistently.
Letting information in these tables persist between tests seems
harmless. Tests that need these tables reset can simply add them
to the tablesUsed array.
This is needed for unit tests to work with the new MCR schema.

So we can make the job voting, preventing other tests from regressing.
These tests can be re-enabled whenever they're made to pass.
