[David Teller [:Yoric] - still alive but not very active]

As described in https://dutherenverseauborddelatable.wordpress.com/2014/05/30/revisiting-uncaught-asynchronous-errors-in-the-mozilla-platform/, we are in the process of turning uncaught promise rejections into oranges.

We have managed to fix most of the existing tests that leave uncaught promise rejections, but there are several DevTools tests that still need fixing before we can land bug 1016387. Opening this bug to follow the work.

Here's an up to date run of what happens when all rejection whitelisting is removed from DevTools:

We're actually quite close all things considered!  A final push to fix what remains seems worth doing.
