[0.9.1] Construction timer resets after cancelling in queue

[Rwn]

When you start building an item, then queue other items, then cancel these items, the "timer" for the first one is reset.

For example :
- Start building a pumpjack
- Queue some other items
- Wait for the pumpjack to be half completed
- Cancel the other items
- Building the pumpjack starts over from the beginning

Illogical

Should be fixed

Thanks for the report, this will be fixed in the 0.9.2.
