A located post's author deletes it

A located post's card had no action at all, so whoever wrote one (with this device's position) could not take it back
from the app. The persona's own located card now has Delete, which asks first, without the line about other servers
(a located post never left PrivaPub), and goes through /clientapi/post/delete, since the Mastodon API looks past
located posts. The globe's end-to-end test deletes the post it writes this way.
