Bug: Missing taxes for undiscounted prices when creating the order from draft

[korycins]

What are you trying to achieve?

I try to receive the taxes calculated for undiscounted prices when creating the order from draft

Steps to reproduce the problem

1. set up the taxes (flat rate / tax app/ tax plugin)
2. create the order from draft and include some discounted products
3. the undiscounted values will not have calculated taxes

What did you expect to happen?

When creating the order from checkout, the taxes are calculated for undiscounted prices. It doesn't work in that way when order is created from draft. The undiscounted returns the same value for gross and net field.
