No error indication when URL is not a feed
Steps to reproduce
- Add a new feed with wrong url
- See that there is no error message
Reproducible in:
- Flatpak unstable: not sure how to get the CI artifacts
- Other: Flathub
Current behavior
I added the feed and got no message except fetching new episodes which it can't do. Worst is, I can't remove the URL either because it's not shown as a show.
Expected behavior
Do not add a feed that can't be parsed or ask the user for confirmation
