Simplify tabs for incomplete order.

The tabs which did something different for an incomplete order vs. a
complete order led to a lot of confusion.

The javascript form submit would also cause some confusion in
functionality.  If for example, I was on "Order Details" and clicked on
the "Payments" link, the "Order Details" form would be submitted, and I
would be taken to the "Customer Details" page, when I actually wanted
to go to the "Payments" page.

This reverts commit 318b820114d6d631e9be6ddb500e6a234612407f.

This is causing build breakages:
