[entities] Add a safety belt avoid unexpected error in some corner case e.g. while debugging an instance I attempted to display result of 'Any X, C WHERE X container C' with unexpectedly to container for the entity, but I wasn't able to display it because raised an error since len(rset) was 2. Even if the caller may be wrong, it seems ok to not call if function is called in an erroneous context and simply return None in such case.
