Impossible to cancel upload of large number of files without deleting app data

### ⚠️ Before posting ⚠️

- [x] This is a **bug**, not a question or an enhancement.
- [x] I've [searched for similar issues](https://github.com/nextcloud/android/issues) and didn't find a duplicate.
- [x] I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".

### Steps to reproduce

1. Select a large number of files to upload, e.g. few thousand.
2. Go to upload file list to try to cancel the upload.
3. The list takes ages to load and makes the UI mostly unresponsive. Clicking on the big X does nothing. Clicking on X on individual files either does nothing or reacts after a few minutes.
4. Due to the above it's impossible to cancel the upload, which also means unable to upload new files. Only clearing app data resolves the issue.

### Expected behaviour

The uploading files list should not be rendered all at once, but lazily loaded. The UI should be responsive to the user.

### Actual behaviour

The app UI is frozen making any actions unavailable.
