Fix shade not opening after opening widgets on lockscreen

The ShadeTouchHandler sends touches to NSWVC in order to open the shade
while the hub is opened from lock screen. However, this means that the
GlanceableHubContainerController can see and intercept the touches
intended only for the shade, which causes the shade to not open.

This change prevents the hub from seeing these touches. Long-term, the
scene container will handle these actions instead.
