[Android] TapGestureRecognizer do not fire the tapped event on "normal" tap/click.

Bug report best practices: https://github.com/xamarin/Xamarin.Forms/wiki/Submitting-Issues

Description

On Android the TapGestureRecognizer do not fire the tapped event on "normal" tap/click. The finger is always sliding a little over the screen when you are tapping it, the TapGestureRecognizer have a very small "sliding"-tolerance. This makes the TapGestureRecognizer to only fire a tapped event if you click much more carefully than on a normal button.

Steps to Reproduce

1. Device: Samsung SM-T580 (Galaxy Tab A)
2. OS: Android 7.0
3. Enable developer options: Show Touches and Show Pointer location.

Create any basic Xamarin.Forms project and apply a TapGestureRecognizer to any basic element (Text, StackLayout etc.)

Expected Behavior

The tapped event should be fired even if a little sliding occurs, just like normal buttons do.

Actual Behavior

No event is fired when a little sliding occurs, like it does on buttons.
