[2.0.13] Busy personal bot gets repair job instead of free one

[jkaps9]

What did you do?
Dropped a gun turret with less than full health for my personal robots to repair.

Steps to reproduce:
1) turn off personal Roboport
2) have a placed (already on the map) tank or gun turret that is damaged
3) have a damaged tank or gun turret in inventory
4) have sufficient robots and repair packs in personal inventory (I did this with 8 robots and 100+ repair packs in inventory)
5) turn on the personal Roboport
- a robot will deploy to repair the placed tank or gun turret
6) open inventory, pick the damaged structure, and place it on the map
- the deployed robot will add the new repair job to its queue instead of an available robot deploying. this can be particularly time consuming as the tank can take a while to repair.

What happened?
An already deployed robot that was repairing my tank or another gun turret finished repairing the tank or other gun turret and then repaired the newly dropped damaged gun turret or tank.

What did you expect to happen instead?
One of my other robots in inventory would repair the turret.

Does it happen always, once, or sometimes?
Always
