Show cached posts in the portrait bar while fetching new from server
The portrait feed will now load posts from 00:00 of two days ago to allow caching. The previous implementation was fetching posts from now() - 2 days
causing a cache miss every time because the parameter was changing each second. (!1369 (diffs))
We want to show the cached posts while we are fetching the new ones from the server. We can't just use the fetchLocalThenRemote method directly because we are grouping and ordering the posts before displaying them.
