mFormAssistPopup is null?

I also couldn't reproduce this on a Galaxy Nexus, but it looks like onConfigurationChanged() is getting called before initializing mFormAssistPopup, which means it's getting called before initialize(). I think a null check is the right fix for this problem.

We also call refreshActionBar() in onConfigurationChanged(), which references mBrowserToolbar, but that's initialized in onCreate(), so we shouldn't get a NPE in that case.

Let's find out if this is blocking fennec 1.0 before approving for Aurora 14.

[Triage Comment]
Still hasn't gone through blocking triage, but I can't imagine we'd want to leave this very reproducible startup crash unfixed, so I'm just going to approve for Aurora 14.
