color-device: Make it possible to outlive the active monitors

Browse Source 
Previously the color device was destroyed when it was attached to a
monitor that was going away. However, the MetaMonitor objects are
ref-counted and can stay around for longer, even if the underlying
resources went away. We need color devices for as long as the
MetaMonitors are alive.
