Make the checkbox id more unique.

If the swagger.json defines more than one oauth2 Security scheme with
matching scopes, the id of the scope checkboxes were not unique.
As a result the scope for a second security scheme could not be
selected.

By adding the security scheme name to the id, it becomes more unique.
