If an expection is thrown in the activate phase, the service worker should be terminated

[signorpipo]

Right now, nothing happens, but since on activate u can do stuff like move from a temp cache to a proper one and then delete the temp cache, if an exception is thrown the service worker will be in a "not completed" state, but will control the page anyway, which could lead to unexpected bugs

My solution right is to try catch the activate and do:

    let clients = await self.clients.matchAll();
      await self.registration.unregister();
      clients.forEach(client => client.navigate(client.url));

which seems to work, but there is another bug I added which might make it fail: #1687

To me, it seems like an expectation should abort the service worker, and if u don't want that, u can always try catch it and do nothing to prevent the "abort".
Or an option to abort the service worker should be added so we can call it on activate.
