When loading new items on an empty list ocreader is crashing

[Lakrimar]

Description of the issue

When opening the app and refreshing it to load new issues the app crashes when the list was empty before. When reopening the app the new items are listed correctly.

Expected behavior

OCReader should display new items instead of crashing...

Steps to reproduce

1. Open OCReader
2. Recognize an empty list
3. Refresh to load new items (swipe from top to bottom)

Your Environment

• OCReader version: 0.47
• Nextcloud news version: 14.1.11
• Android version: LOS 16 (Android 9)
