Firebase out of date

[joshspicer]

The firebase library is 2 major versions out of date.

When running the app, you'll probably get stuck on this screen for ~5 minutes when updating with yarn.

This can be fixed by updating firebase library. Since we are two major versions behind, there are several breaking changes. We can consider doing this (or not). I haven't observed anything broken with the subset of firebase features we're using.
