Successfully gets build to pass!

+ The issue: Our jest runner for our tests does not play nice with the react-native-vector-icons Icon object on the build machine. So we override the Icon constructor post-installation like this thread explains:

Worth noting: locally, everything worked fine. The issue was specific to the build machine, as far as I could assess.
