The unit test for the new ship-it dialog that attempted to change the

confirmation preference must have been written while the user sessions

settings code was still in flux, and wasn't properly skipping the code

that actually saved the setting. This resulted in a bad PUT to the

server and the ship-it dialog being permanently visible on the screen.
This change fixes the test so the storeSettings() method isn't

actually invoked, but resolves the promise, allowing things to proceed.

Ran js-tests.
