[0.8.7] Crash when opening article after mark newer item as read

[nRaecheR]

The current version of the app (0.8.7) crashes when you open an article after you marked an newer article as read.

Steps to reproduce :

1. Set item sorting to new -> old
2. Set feed layout to "Erweitert (enhanced ?)"

The two steps above may be optional.

1. Open an folder with articles with mutiple unread items
2. tap on the "Mark as read" checkbox of an article at the top of the list
3. Open the item below the previous one

Tested on Samsung GT-i9505, Android 4.4.2.

I should add to this that I've enabled the option "Show unread items only", I suspect that this is the culprit.

I can confirm this bug.
