Summary:
This fixes a cryptic bug to appear when you try to use scrollResponderZoomTo in Android.
before this PR it would break with a `Error: TaskQueue: Error with task : invariant requires an error message argument` because the invariant() was not properly used..
Also, instead of detecting the platform, I think it's better practice to duck type.
