Tests failing with no stack trace (via Invariant)

[bdickason]

Have spent about the last 1.5 hours trying to find a way to resolve this test failure. The stack trace doesn't mention a specific module, but it has to do with how we import/export modules.

I'm not familiar enough with the codebase to find the specific module, but I suspect either one of them was not properly imported with { } around the module name (or vice versa), or a module was not exported w/ default.

See: https://stackoverflow.com/questions/34130539/uncaught-error-invariant-violation-element-type-is-invalid-expected-a-string

Unfortunately there is no useful stack trace, otherwise I'd have fixed this very quickly :(

Any ideas where I should start looking?

Here are the changes I've made to resolve a few of the test issues and get to this state:
