Construction Terminated: Area Blocked -- Doesn't remove building ghost

[Brian-Catcow-B]

Description

If a constructor tries building something but the area is blocked by a unit from doing so, often it will leave the ghost of the building as though the constructor will still try to build it, despite the builder's queue being updated to not contain that structure.

Things are properly cleaned up when a constructor dies, but other ways of being unable to build something should be checked, such as, but not limited to: Couldn't get there, unit cap, terrain deformation before build attempt.

Expected Behaviour

When the constructor's queue is updated to remove a building, the ghost of the building should disappear.

Actual Behaviour

Sometimes the ghost sticks around

Reproduction steps

The most common way I've found this to happen is when I have a T1 constructor bot build a field of construction turrets while a T2 bot is standing in the middle of the field of construction turrets, building an advanced fusion reactor. The T2 con doesn't move out of the way and the construction turret ghosts stick around despite the T1 con deciding to not build them.
