Split SchemaTableServiceIT into targetted tests

Along with a careful look at everywhere that imports TreeService. I am mildly more confident I didn't miss any this time.  

BasicInfoSchemaTables already has a unit test so remove duplication.

ServerSchemaTables now has it's own IT.

StorageSchemaTables now has it's own IT, which derives from PersistitITBase as it is a Persistit-only set of views.
