UI Error when moving build order from blacksmith queue

[kanneblei]

Summary:
When changing amount of ingots produced and moving them, I got a double UI error. Namely, the backtraces were:

release-524 (x64)

And:

They both showed up at the same time.

Steps to reproduce:

I did not manage to reproduce the issue following these steps, but at the time, what I did was:

1. I was scheduled to maintain 3 steel ingots in stock.
2. I clicked that order, changed it to maintain 5 ingots instead and clicked craft again
3. I moved the old order to the trash
4. I tried to move the new order up, which triggered it.
