Better naming for exported render function in test-utils

[andrewebdev]

In utils/test-utils.tsx, a custom render function is created to wrap the apollo provider. This function is later exported as render. I feel this should rather be something like renderWithAuth. This is because, the basic react testing framework render function is also called render. Having the same name, but with different behaviours, is bound to trip someone up in future.

@andrewebdev sounds good to me. Actually, I can make that change in the branch I'm currently working on, since it's such a small change, it won't add much to the updated pages.
