[gnome-color-manager] Set the 'remote-profile-hash' sensor option when calibration has completed

[Richard Hughes <rhughes src gnome org>]

commit 331c3830c57e7df2e89137584bcf80876002d8e2

    Set the 'remote-profile-hash' sensor option when calibration has completed
    
    This allows us to automatically import the profile in future versions of
    gnome-settings-daemon.
