We assume that "Intent:GetHandlers" will always work, but GeckoView does not implement it, and may never implement it. This causes the JSON.parse to throw and breaks the initialization of many other parts of code. Effectively killing GeckoView.

In the long term, I want to split out code from browser.js into 3 code paths:
* Firefox (default)
* WebApp
* GeckoView

Some parts of the code won't be needed for WebApps and GeckoView, so let's not even add it.

In the meantime, this fixes the current problem. With this patch, GeckoView example apps work on everything but the Nexus 4 (bug 921792)

Early return instead?
