Patch from Jeff Davis (SITKA) fixing cardless patron updates

Quoth the bug report (https://bugs.launchpad.net/evergreen/+bug/851110):

  On our Evergreen 2.0.8 system, it sometimes arises that a patron's card gets deleted. If it was the patron's only card, it becomes impossible to add a new card to the account via the staff client.

  How to reproduce:
  1. Retrieve a patron record for a patron who has no associated card.
  2. Click the Edit button.
  3. Click Replace Barcode and enter a new barcode.
  4. Click Save. This does not work - the process hangs, and if you hit Reload, you will find that your changes were not saved.

  I believe this happens because some code in register.js assumes the patron has at least one card. I have a potential fix that this comment box is too small to contain ... uh, that is to say, I will post it momentarily.

Which he did, and I applied.
