[cab]

Adds a selector (authenticatingSelector) to test if the user session is being loaded, and a LoadingComponent option to render during that time.

Fixes #30.

@cab Thanks this is exactly what I had in mind! Could we extend your test to verify that a custom component is actually rendered in the isLoading branch?

Should be able to use something like this to just check if the LoadingComponent is rendered in the DOM. And we can use the override for the LoadingComponent option

Glad to hear that! And yeah, sure thing!
