Since Android 15, tapping single note widget sometimes creates "New note" instead of opening the linked note

[jancborchardt]

Please make a clear and concise description of what the bug is.

Steps to reproduce

1. Use the single note widget
2. Tap on it

Expected behaviour

It always opens the linked note.

Actual behaviour

Since Android 15, it sometimes (not sure when) creates a "New note" and opens that.
In Android 14 already it sometimes opened the list of notes instead of the linked note, but this new, also erroneous behavior is a bit worse and more annoying. ;)

Server

Please complete the following information.

• Notes app version: 4.11.0
• Nextcloud version: 31.0.7

Just tested the current play store versions of Notes and Nextcloud on Android 12 and the single note widget works fine.
I have also previously used Notes v4.3.1 and earlier on Android 15 and 16 with no widget problems.
With the release of v4.4.0 the widget opens a new note every time, so it seems to be a combination of Android 15+ and the code being converted from Java to Kotlin.

Similar to #2748

I was wrong about the Java to Kotlin thing, I tried replacing the .kt with the original .java widget and it made no difference.
After checking out v4.3.1 and compiling it, everything works properly again on Android 16. It is also OK after changing the target sdk to 35 and updating the dependencies to match the current main branch.
So something else in the notes app code which changed between 4.3.1 and 4.4.0 is causing it (maybe :) ).

It seems this is the change which has prevented the note id being kept in the extras:

Commenting those lines out fixes the single note and note list widgets for me on Android 16. I don't get any exception thrown about implicit intent but I am unsure whether that problem would apply to these widgets.
