Fix launch not to wipe out target sector updates

Launching ABMs updates their base, in mission_pln_equip().  The update
got wiped out when launch_missile() wrote back the target sector,
triggering a seqno mismatch oops.  Harmless with the stock game's
ABMs, because they use neither shells nor petrol.

Fix by re-reading the target sector.
