/*
* Fixes a corner case in which the app wasn't returning the latest data.
* You can reproduce the corner case by commenting out the line below and
* then doing the following steps: 1) load app for first time so that the
* initial New York City data is shown 2) press the refresh button on the
* app 3) go offline 4) reload the app. You expect to see the newer NYC
* data, but you actually see the initial data. This happens because the
* service worker is not yet activated. The code below essentially lets
* you activate the service worker faster.
