TwitterCard meta tags are supposed to use the attributes "name" and "content".
OpenGraph tags use the attributes "property" and "content".
Twitter itself is smart enough to detect broken meta tags and discover the TwitterCard
using "property" and "content", but other platforms that only implement parsing of TwitterCards
and not OpenGraph may fail to correctly detect the tags as they're under the wrong attributes.

`context` fields for objects and activities can now be generated based
on the object/activity `inReplyTo` field or its ActivityPub ID, as a
fallback method in cases where `context` fields are missing for incoming
activities and objects.
When doing prune_objects, it's possible that bookmarked objects are deleted.
This gave problems when fetching the bookmark TL.
Here we clean up the bookmarks during pruning in the case were it's possible that bookmarked objects are deleted.
weird values in href will cause base64 encoding to fail later down the
line, so let's make sure the value we're passing on is somewhat sane, or
at the very least a binary
this fixes #482
When no image description is filled in, Pleroma allowed fallbacks.
Those were (based on a setting) either the filename, or a fixed description.
Neither are good options for image descriptions imo, so here we remove this.
Note that there's two tests removed who supposedly tested something else.
But examining closer, they didn't seem to test what they claimed to test,
so I removed them rather than try to "fix" them.
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.
