Deleted modules appear in my favs, and can't be removed from there

[akarelas]

I'm KARJALA, so you can see that Pinto-Common and Mojo-Facebook appear on this page: https://v1.metacpan.org/author/KARJALA

However there's no way to remove the ++ from those modules. The link to those modules takes me to a 404 page.

Please fix somehow.

from IRC:
15:31:09 � ranguard� because technically those modules are now in backpan

we should look into how we handle backpan links there.
