[FIX] account: restore "outstanding" ID

Steps to reproduce
------------------
* go create an invoice for a customer that has outstanding credits.
* in the blue message at the top, click the "outstanding credits" text
  in bold.

You should see that you're taken to the home page. We expect to be taken
to the bottom of the invoice, where the outstanding credits are
displayed.

Cause
-----
A static HTML ID was mistaken for a variable in
d682871a8b.
