When editing user roles, cancel should reset your selections

When logged in as an admin editing a user profile you now see a list of checkboxes for all of the available user roles. When you make changes to the user roles save and cancel buttons appear. When cancel is clicked your changes should be reverted

I think the correct action here is for the cancel button to bring the user back to the previous page without saving any changes.
