Service worker API `navigator.serviceWorker.register` can fail in multiple ways.
For example, in Chrome, with an unstable network connection you can have the
following error: `An unknown error occurred when fetching the script.`
In the current state, it creates an `Uncaught (in promise) TypeError:` style of
error, which cannot be caught by the user on his own.
I think it's better to log the error over raising an error that cannot be
caught.
