Fix artisan routes Output

I noticed after changing my api routes to use Route::api(), that when I ran artisan routes those routes were gone. So did some poking around, and I believe I came up with a solution that resolves the issue. 

Tested it in one of my projects, and artisan routes is returning the correct input.

Hopefully the test I added adequately covers the change, if not let me know and I can add another test or two.. after I think of them.
