Manual file upload must have priority over auto-upload queue (file stuck in queue for hours)

**Is your feature request related to a problem? Please describe.**

After reenabling auto-upload in the nextcloud app (because it was deleted due to a software bug) I now have a upload queue of about 3000 files.

I just added a 1KB textfile to be uploaded to a nextcloud folder, which I assumed will be uploaded instantly.
After realizing the file is still not uploaded after 5 minutes, I found the textfile at THE END OF THE 3000 FILES QUEUE in the app.

**So now I have to wait several hours for a 1KB textfile to upload.**

**Describe the solution you'd like**

If the USER triggers a new upload manually (by selecting a file in app or using the android SHARE function using nextcloud there), this upload should be prioritized and therefore put ON TOP OF THE CURRENT UPLOAD QUEUE.

I'd consider this issue as a bug rather than a feature, personally, but don't wanna be to pushy here.

**Describe alternatives you've considered**

Not using the Android nextcloud app because it has unfixed open issues for years and numerous problems... Actual alternative is using a android web browser to access nextcloud.
