[FIXED] Delayed building actions are always executed, even if they are done.

[sanderd17]

When you assign delayed building actions to a unit (with SHIFT+CLICK), it gets always executed, even if the building is done.

How to reproduce?

1. Take 1 unit
   
2. Let him build two buildings (preferably, buildings that take moderately long, like barracks) via SHIFT+CLICK
   
3. Assign a bunch of other units to the second building he had to build
   
4. The second building will finish faster than the first one
   
5. When the first building is also finished, that one unit you used to construct the foundations of the buildings will run over to the second building and start hammering on it
   

The unit also can't be seen when using "idle" state search, and will never finish his job (so even if you assign a new job via SHIFT+CLICK, he won't react)
