`postMessage('claim')` followed by `waitForControlled(win)` was used instead of
calling `clients.claim()` in a Service Worker's `activate` event handler; this
invocation of the event handler was not reliable due to resurrection
(resurrected active workers won't receive an `activate` event). This is no
longer necessary with resurrection removed.
