Reject invalid ranges

[bilthon]

While testing ranges I was able to make mostro accept an order in which the min_amount > max_amount. The web client will prevent this from happening, but ideally these kinds of orders should also be rejected by mostrod in case other clients fail to catch this.

Here's a sample event that was accepted by mostro:
