List of RSS feeds doesn't update when feed is removed
The list of RSS feeds doesn't update when the feed is removed by unsubscribing via the feed's overflow menu, rather than using the delete button in the list of RSS feeds.
Steps to reproduce:
- Add an RSS feed
- Tap the entry in the list of RSS feeds to open the feed
- Unsubscribe via the overflow menu ("Remove blog")
- Expected: The list of RSS feeds is shown, it's now empty
- Actual: The list of RSS feeds is show, it still contains the removed feed. Tapping the feed again causes a NoSuchGroupException (error toast, no crash)
