parsing: Default to has_stable_ids = True

While the correct behaviour is to have stable ids False since that
is the case for the majority of the sources, setting this to True
temporarily before #1954 is fixed. Handling sources without stable
ids automatically requires new curator API endpoints which haven't
been merged to -stable yet.
