COMPASS-619: Fix error notification icon path on Linux (#761) (#800)

* Remove old references in metrics to mixpanel

* COMPASS-619: Fix error notification icon path on Linux

This fixes the observed behavior on Linux which boils down to:

> [An unexpected error occurs on Linux when trying to tell the user
that a different unexpected error occurred][COMPASS-619]

Thanks to @pzrq’s screenshot, we can see this error is coming from
`src/app/metrics/index.js`:

Cannot+read+property+%27win32%27+of+undefined.png)

## Developer Notes

The `config.hadron.build` key is removed from the package.json we ship
to customers at build time.  Please see [`transformPackageJson()` in
hadron-build](https://github.com/mongodb-js/hadron-build/blob/2434019288
c7cf3aa66e0fbc05ccb98c8a8eee47/commands/release.js#L239-L268) for more
details.
