It stops importing characters after encountering a corrupted card

[Devansh-kajve]

Describe the bug
If you import multiple characters at once and one of them is corrupted/not getting imported for any reason then the importing stops at that card and others after it don't get imported. Also if you then try to import them again then first the previous remaining ones are imported and then the current ones, creating duplicates.

To Reproduce
Steps to reproduce the behavior:

1. Click on import.
2. Choose multiple files in dialog and click import.
3. If you have a corrupted/not working file in the files then the importing will stop on encountering it and the others in queue after it won't be imported.

Expected behavior
If it encounters a corrupted file then either it should continue and import the other files that are working or it should stop like now but clear the importing queue so that if a person tries again then duplicates are not created.
