Steps to reproduce

Take an existing library with some downloads. Create a backup. Then, uninstall and reinstall Mihon, select the same app folder, restore the backup.

Expected behavior

Already-downloaded chapters should still be displayed as downloaded.

Actual behavior

All chapters are displayed as not downloaded, even if they have been. Trying to download an already-downloaded chapter causes an error.

The user has to navigate to advanced settings and use the "invalidate download cache" option. After they do this, the correct state is displayed.

As far as I can tell, the correct behavior is straightforwardly that the download cache needs to be invalidated when the user restores a backup. It's clearly always going to be wrong to trust a newly-created empty downloads cache when there are in fact already downloads.
