upload does not stop after token revoke & labeling of the notification seems misleading

### Steps to reproduce
1. setup some auto-upload stuff
2. Revoke token for your mobile or trigger a remote wipe (I did the latter!)
3. add some more files into the folders marked for auto-upload

### Expected behavior
- auto-upload stops
- auto-upload settings being removed as well (for all paths pointing to that account; I only use one account, but IIRC you can have multiple)

### Actual behavior
- still tries to auto-upload
- one notification per failed upload:
 (I downscaled the screenshot a bit)
[German→English) "Upload failed, pls. login again"; "Incorrect Username or Password"

**This raises the question: Incorrect labeling or are my Username&Password stored on the mobile device!? I thought all devices are handled using tokens, and the password is never stored on any of them.**
I hope this is just a "literals" bug. (or maybe a translation error from the past? Would be awkward, but relieving, if that's the case…)

### Environment data
Android version: 9

Nextcloud app version: 3.18.0

### Logs

#### Nextcloud log (data/nextcloud.log)
Just stuff like "Login failed for xxx" (because obviously, the token isn't valid anymore).
