Admin allows saving ticket urls without "http(s)://"

[hmpf]

This makes it hard using the content of a ticket url for a link later.

Classic frontend tackles this, new frontend does not.

I have checked this out and if using the frontend to set the ticket url it will silently fail if adding something that is not a url (e.g. "abc"), but it will not add it to the incident. When adding a url that does not have http(s):// in front of it (e.g. "www.example.com") it will convert it to "http://www.example.com".

Should anything from the behavior of the frontend be changed? Or is the problem purely in the admin?
