Hey folks!

I've noticed that wp theme list doesn't include broken themes.

How to reproduce

1. Install theme Buntu - wp theme install buntu which installs the parent theme stargazer as well.
2. Check theme list to see the new themes added.
3. Delete the parent theme stargazer - wp theme delete stargazer
4. Check theme list. The child theme is missing. But present inside themes directory and on WPADMIN under Broken Themes section.

Since the theme files are present and not list in CLI, try to install the theme again will result in an error.

Here are some screenshots.
