[Freeciv-Dev] (PR#13630) build city on fortified unit destroys unit

["Jeffrey Sullivan" <jeffrey.mudge.sullivan@xxxxxxxxx>]

I was playing the latest version of FreeCiv and noticed an odd
behavior: if I sent out a unit (only tried this with archer),
fortified on a choice city-building spot, then built the city on the
unit later (when a settler was available), the unit just disappeared.
I haven't played a whole lot yet, but I checked the bug tracker and
couldn't find anything similar, so here you go.
