Removed the suggestion from the Comms screen that Phoebe's name is unknown.

I think this might partly be because of my dialog changes, but this
causes a minor continuity error, since the mission clearly states
that you're rescuing "Phoebe Lexx", and there's also the fact that
the indicator now says "Phoebe" instead of "Target". I figure just
make her name known from the start; the explanation can be that the
ship automatically transmits the name.
