It was possible for the `routes.name` field to be `NULL`, causing
`name_was` to be `nil` after a rename, resulting a bad first argument to
`sub` when attempting to rename descendants. This change adds a
condition to make sure `name_was` is present before attempting the
descendant update.

With the changes in Gitlab::VisibilityLevel it is no longer needed to
explicit conversion to Integer in the controller itself.

When a VisibilityLevel is an integer formatted as a string, convert it
to an integer, instead of looking it up in the hash map.

When the value is not recognized, default to PRIVATE.

Ensure the correct "Public" radio is selected by choosing it on ID.
