[BUG]: Restricting cleartext network traffic breaks import and statistics pages

### Checked for duplicates?

- [X] This issue is not a duplicate

### Does it also happen in the desktop version?

- [ ] This bug does not occur in the latest version of Anki

### What are the steps to reproduce this bug?

Restrict cleartext network traffic globally on your device (which blocks all non-TLS traffic). Open Ankidroid and try importing a deck from a local file or visit statistics page.

### Expected behaviour

The import page (after choosing a local deck package file) and statistics page should be accessible

### Actual behaviour

A blank page with "TypeError: failed to fetch" message is shown instead of import page and statistics page.
