Properly handle a missing parent folder. (#188)

During sync, gracefully handle the situation that an entity's parent folder is missing. This can happen temporarily while we are still retrieving data, for instance. Without this change, the sync will abort and fail, even if the parent folder is actually there and would be added in later.
