Prevent URL trailing char errors in VIM/WIM

It is very common for users to copy/paste the URL in the web GUI form
when registering new VIMs/WIMs.
This can be error prone, since it might introduce trailing characters
that might pass unnoticed (e.g. when copying from "OpenStack Rocky >
Project > API Access" a trailing space will be introduced).

This change tries to prevent that from happening.
