Steps to reproduce

1. Install and setup new account in Nextcloud app
2. Navigate into Photos folder
3. Select all items and add to favourites
4. Switch to Favourites tab
5. Long-press on any item; select all
6. Select Copy or Move from action menu
7. In Copy to… dialogue create new folder (e.g. A)
8. Confirm move/copy

Expected behaviour

Selected items are moved or copied to selected folder.

Actual behaviour

After a suspiciously jumpy loading animation the app crashes. When examining what files have been copied/moved, there is always a subset of the selected files present.

Not reproducible with the latest master version.

Closing this issue as there have been major changes made to the way the recycler view, its items and the corresponding positions are handled internally.
