'gatsby develop' requires restarting to load new component files

[LemuelCushing]

Spotted while going through gatsbyjs.org/tutorial/part-one -

Even though the corresponding js file has been created under pages, trying to access it routes to the development 404 page. The link to the new component is available on the Pages list at the bottom, yet clicking on it takes me back to the same 404 page.

Only after killing the process and running gatsby develop again do the new pages work.

Environment

Gatsby version: 1.1.27
Node.js version: 8.5.0
Operating System: Win10

How to reproduce:

Follow the tutorial to the tee, after creating page-2.js the result will differ from the one described in the tutorial.
