[BUG] Default `minimum_service` model produces utilisation factors < minimums

[alexdewar]

I noticed this while working on #328. It may be a bug introduced by my changes (though I don't think so), but I'm opening this issue so I don't forget about it.

The error message I get when running the minimum_service model (using code from #328) is:

Exception has occurred: ValueError
Utilization factors must all be greater than or equal to
                          their corresponding minimum service factors. Please check
