fix(push): stop handling the clear push in the service worker

The worker answered a `type: "clear"` push by closing the dose
reminder for that slot and showing nothing. Browsers do not allow a push
without a visible notification on a subscription that promised one:
Safari removes the subscription after a few, Chromium shows its own
"updated in the background" notice. The server no longer sends it, so
the branch and its tests go; a reminder stays until it is tapped or the
next reminder with the same tag replaces it.
