trim-template: Fix handling long named templates

Browse Source 
Trim template name to fit full VM name in 31 chars.
At the same time, check if the VM already exists - if so - remove it
first (or error out asking the user to remove it manually - if VM isn't
marked as internal).
Now that VM is created as internal, to skip appmenus creation.
