Clear keyboard accessory suggestions on reload

Before this CL, the accessory would only clear the accessory suggestions
when the origin changes during a navigation or when new suggestions
overwrite the existing ones.
With this CL, the accessory also clears the suggestions when a reload
was the reason for a page navigation.
