Some default web favicons not loading properly

[jacobgkau]

The Amazon and Crates.io icons loaded properly as of #42, and still show up on my main work machine where they're cached:

However, on a fresh machine/fresh account without a cache, they're currently showing the Google API's default icon for when a website doesn't have a favicon:

This happens on d17acbd (not caused by #95, but still happening there too as of right now.)

Worth noting that it's possible something changed on the Google API's end, or else something changed between #42 and now that was missed.
