synchronization error / different content rich mode <-> text mode.

This issue respects the following points:

• I have read the FAQ
• I have searched for existing issues
• The issue affects the Notes Android app, neither the Notes server app nor the Nextcloud Android app.

Describe the bug

When loading the app most of the times an error message appears (see below).

Sometimes also the error appears that rich editing mode could not be loaded.

Also I found I have different content in text mode and rich mode on my shopping list, so now some things I am thinking my bag ;)

Thank you for the App!

Expected behavior

No synchronization error.

Start with NotesServerSyncTask.java, especially run() at line 99 and pushLocalChanges() at line 150, then reproduce the synchronization error and compare the shopping list in rich and text modes. Done means synchronization completes without the reported lock error and both modes show the same content.
