When credit card error, the cart view shows prices like '$#Price:0x00007f9e2c023f88'

Actual

1. Put in junk credit card
2. Place order
3. When you see error validation message, prices look like '$#Price:0x00007f9e2c023f88'

Tested on staging and works as advertised: proper read-only label shows up.

Thought, it would be better if the error sent you back to the /cart view where you actually see text inputs to change product quantities. But, that will be left for later.

@thermistor actually it looks like this critically broke order checkout. :( While testing on staging and placing an order for Ohio Valley Food Connection via Purchase Order I got this error: https://rollbar.com/LocalOrbit/Local-Orbit/items/575/?item_page=0&item_count=100&#traceback

We really need to get tests green. Something as basic as placing a successful order needs to be caught before a PR goes up.
