revert Use same context for quote posts as the post that's being quoted (#379)
See https://akkoma.dev/AkkomaGang/akkoma/pulls/350#issuecomment-6109
When making quotes through Mast-API, they will now have the same context as the quoted post. This also results in them being showed when fetching the thread. I checked Misskey to see how it's there, and they show the quotes there as well, see e.g. <https://mk.toast.cafe/notes/98u1g0tulg>.
An example from Akkoma:

E.g. Flag activities have an array of objects
We prune the activity when NONE of the objects can be found
Note that the cost of finding and deleting these is ~4x higher than finding and deleting the non-array ones
Only string:
Delete on activities (cost=506573.48..506580.38 rows=0 width=0)
Only Array:
Delete on activities (cost=3570359.68..4276365.34 rows=0 width=0)
(They are still executed separately, so the total cost is the sum of the two)
We add an option to also prune remote activities who don't have existing objects any more they reference.
Rn, we only check for activities who only reference one object, not an array or embeded object.
By default Postgresql first restores the data and then the indexes when dumping and restoring the database.
Restoring index activities_visibility_index took a very long time.
users_ap_id_COALESCE_follower_address_index was later added because having this could speed up the restoration tremendously.
The problem now is that restoration apparently happens in alphabetical order, so this new index wasn't created yet
by the time activities_visibility_index needed it.
There were several work-arounds which included more complex steps during backup/restore.
By renaming this index, it should be restored first and thus activities_visibility_index can make use of it.
This speeds up restoration significantly without requiring more complex or unexpected steps from people.
