[Mike Conley (:mconley) (:⚙️)]

Attachment: Bug 1648886 - Fix some busted tests for the about:home startup cache. r?amy!

When the tests for the about:home startup cache were first introduced, I made
a few mistakes:

1. I used the wrong format for default named arguments in JavaScript. I accidentally
   used { namedArg1, namedArg2 } = { namedArg1: "default1", namedArg2: "default2" }
   instead of { namedArg1 = "default1", namedArg2 = "default2" } = {}.
2. Some of the tests were passing a boolean as the second argument to simulateRestart,
   which is not expected. This caused a whole host of issues, including some tests
   not waiting for the cache to be ready when doing the restart simulation.

(2) is what ultimately caused the intermittent failure for bug 1648886 - sometimes
the about:home startup cache would "win" the race and the cache data would be
available, and sometimes it would "lose" the race. Now we correctly wait for
the cache to be available before proceeding with the test so that the cache
"wins" every time.

Thanks for the patch mconley! I am out of office the rest of the week, but I'll be able to review once I get back.
