messageTray: Add removeAction() method and allow references to actions
Internally in gnome-shell it may be useful to modify the actions available on a notification while it’s still visible, but without clearing them all and re-creating them. Allow that by returning the action object when adding it, and adding a `removeAction()` method which takes that object and removes it.
