Hélène c1e15ff6f8 Transmogrifier: fix reply context fixing
Incoming Pleroma replies to a Misskey thread were rejected due to a
broken context fix, which caused them to not be visible until a
non-Pleroma user interacted with the replies.

This fix properly sets the post-fix object context to its parent Create
activity as well, if it was changed.
