pw-link: handle link proxy destruction

Browse source 
If for some reason the proxy gets destroyed, we make sure to remove
listeners and forget the proxy pointer. We do not however delete the
target_link; we consider the proxy destruction as an error.

If another definitive state occured on the link (got to paused state,
got an error), then that event will be ignored. Else we consider it an
error.
