[Extensions UI Mac] Fix race condition in showing the icon surfacing bubble

The toolbar icon surfacing bubble shows up the first time the user runs the
browser with the --extension-action-redesign feature.  There's a race condition
in the mac code where if the browser window starts up before the extension
system is ready, the code incorrectly infers that there are no new extensions,
and doesn't show the bubble.  Fix this, and add a test.
