Revert "WIP: Using IdentityCache to store entire Order object"

This reverts commit 71b445a3e4cf1e0ead01b1a14148f7ddc576a4c0.

Playing it safe. Reverting due to jhawthorn's comment here: https://github.com/spree/spree/pull/4887#issuecomment-47491951
Check for adjustments using .any?, given that they're already loaded
Save an order after populator has done its thing

This needs to happen now that order.contents.add no longer persists the objects it adds to the order.

This will do the following things:

1) Check for availability for the line item added
2) Update the order's item total and item count
3) Persist the line item
4) Touch the order
5) Update the totals on the line item
Add tax? helper method to Adjustment
Check for adjustments using any?, rather than exists?
Use in-memory-friendly helpers in the view

Should probably have some kind of presenter logic for this... it's getting out of hand
