App crashing when leaving article activity after a longer time

[nubenum]

When you revisit the article activity via the recents (probably also via the launcher) after a longer time and then go back to search for another article, the app crashes. This happens for me on Android Lollipop/Nexus 5, I don't know if this occurs also on other Android versions. This is especially the case if you're doing some CPU/RAM intensive tasks and then want to return to Aard, so I suppose that Android is killing the search/list activity in some way.

Apart from that, Aard2 is really great and I'm looking forward to the offline images.

Thank you for the report. This doesn't seem to be happenning on Android 4.4. I'll investigate once I get Lollipop.

I think f9d1fb1a42a83baa07e9b0541280549f509bf1e2 should fix this, give it a try
