Use preferred phase to compute wellbore mix for dead wells

Browse Source 
The wellmore mix is set to preferred phase for dead wells, where the
total volumetric rates are zero. This sets the phase of the flow out of
perforations in dead wells and thus avoids zero volumerats for injecting
preforations in dead wells.
