Show the bubble bar edu view

We now show the bubble bar edu view after a request from shell
to show it was received, and as soon as the user performs a touch
gesture on the bubble bar or flyout that causes the bar to be
expanded.

The click listener on the bubble bar is removed with this change
because the input consumer already handles taps. Removing the
listener avoids processing the tap twice which causes the edu view
to not be displayed. Removing the click listener solves the issue
but ideally we should move the edu view to launcher since that
would allow us to manage its state easily.
