Virtual domain ending by `/`

[alex alex]

Bug: When creating a virtual domain ending by / you’re unable to delete or edit it. When editing it, the interface redirects to the virtual domain without /.

Proposal: I agree it’s not a valid domain, but a check should be implemented to disable the creation of a wrong virtual domain.

fix #955 remove / from valid domain characters
