Invalid redirect url validation

[_lucifer_]

The redirect url validation when creating a new app on spotify developer portal does not work correctly for loopback addresses. In particular, it breaks if the rest of the url has a `-` in it.

For instance, it does not accept http://127.0.0.1:8100/settings/music-services/spotify/callback but this works

http://127.0.0.1:8100/settings/musicservices/spotify/callback. Please fix this issue as soon as possible.

The same thing happens to me, I even checked the IETF recommendations definition and it has an example of a longer path.
