Posts made on 1.6.0rc1 seem to have the wrong conversation id (EDIT: apparently this is not the case, see lambda's post below), thus breaking conversation view on other instances, presumably those that only speak OStatus.

Conversation broken as seen on cybre.space (not on 1.6.0rc1):

Can also be seen happening on other OStatus implementations:

• This bug happens on a tagged release and not on master (If you're a user, don't worry about this).
• I searched or browsed the repo’s other issues to ensure this is not a duplicate.
