paused constructor make building under construction not reclaimable until the end

reproduced here : http://content.faforever.com/faf/vault/replay_vault/replay.php?id=6724936
not sure how to formulate that.
have an hives, make it build a building, pause the hive, reclaim the building, it won't disappear and his life will be be stuck at 0 hp. Also construction won't fade away with time. Also if you kill the construction, there is death animation.
if you make hives build something else, then bug disappear on the first building.

also apply on other constructor and not only hives
