'Create Order' with no items creates blank order, doesn't go there

[jimwins]

When a vendor is selected on the reorder but there are no items, 'Create Order' creates an empty order but we don't redirect there

Either 'Create Order' should be disabled when there are no items being reordered, or we should redirect to the blank order so items can be added manually. The latter is what I wanted to do when I ran across this problem.
