Before this change, the widgets recommendation table handles all the
touch events. The table doesn't distinguish a touch event from a scroll
event. This change forwards the motion event to the active recycler view.
If the recycler view doesn't handle the event, it will then forward the
event back to the view hierarchy.
Test: Open the full widgets picker, then start scrolling on the
recommended widgets UI. The full widgets picker scrolls perfectly.
Drag-n-drop a recommended widget
