[bug] Adding any domains to the iframe list breaks logging in completely

[e2489]

Description of the bug

Adding any domains to the list of sites allowed to use Filestash in an iframe results in no longer being able to log in, regardless of how or where. This was mentioned here in an unrelated issue as well.

Step by step instructions to reproduce the bug

Log out of the Filestash front end. Add any domain (http://google.com, for example) to the iframe list. Attempt to log in.

Can you replicate that error from the demo?

Can't add sites to iframe with the demo.

Observed behavior

Upon trying to log in, regardless of how or where, I get a "Not authorised" error.

Expected behavior

I should be able to log in normally. At the very least, the regular frontend (not an iframe) should be working. I don't know why this would break both.
