objectcache: Update tests that are really for ObjectCacheFactory

Most of the logic in ObjectCache.php has been refactored to a proper
factory in ObjectCacheFactory and exposed as a service. These tests
now are really for ObjectCacheFactory, hence the rename.

See: I3179a387486377c6a575d173 (d372626b97).
