    connection: Fix GObject property name
    
    Commit 2e6956e307 turned ConnectionDetails:can-confirm into a GObject
    property, but kept the old JS property name of canConfirm. While
    this worked mostly as we were accessing the property directly, it
    broke the binding the property in the connection dialog.
