Remove old quickshare chip when adding a new one

Fix to avoid showing a quickshare chip based on outdated information.
Resets the pending interaction if the user tapped the old quickshare
chip, since we won't get updated information for that chip.

A future change in QPR3 will fix the logic around retrieving the
quickshare data, so we don't hit this edge case in the first place.

Test: manual; verified that taking two screenshots in quick
succession that result in a quickshare chip no longer showed
two chips at the same time
