handleBlur requires you to touch the screen again to trigger it

When you have an input behind the keyboard that triggers the `container` view's `contentInset` properties to raise it above the keyboard `onFocus` it doesn't return `onBlur`, but rather only once you touch the screen and slightly drag.

Also, this becomes particularly a problem if you have a long form and you are moving from one field to the next (via a handler such as `onSubmitEditing`). The whole form ends up hidden above the visible view area. This is likely related to https://github.com/FaridSafi/react-native-gifted-form/issues/42
where I describe how programatic usage of the `widget.focus()` method doesn't seem to work as well as actually tapping fields.

I'm wondering if anyone knows of something we can call that can trigger it go back immediately on blur??

Reproduce the issue with an input behind the keyboard and inspect the container view's contentInset handling around onFocus and onBlur. Compare a normal field tap with onSubmitEditing and widget.focus() usage, then verify that blur restores the visible form area immediately without requiring a touch or drag.
