Remove unused preliminary entries from ImplRepository::m_aStore again

The comment added to ImplRepository::getDocumentBasicManager by
8e74a57b6cf49cf5296ecc21a111d0119d7cac83 "mib19: #163556# preserve VBA
compatibility in ODF roundtrip" explains why these preliminary entries are
created, but apparently forgot to remove them again when
ImplRepository::impl_createManagerForModel doesn't fill them.
