Not everything in Chrome goes through ChromeActivity (preferences for example).

If we want this to be more universally done, I think we should put it in:

https://cs.chromium.org/chromium/src/chrome/android/java/src/org/chromium/chr...

I think we could put this in pre or post native as it simply sets a boolean.  If
we think there is ever a chance we'll use this before native then let's just do
pre as a "pre"caution (yuk, yuk, yuk)

Done, thanks.  I moved it to 
handlePreNativeInitialization() since the 
LocationProviderFactory is called from native.
