[gatsby-source-wordpress] log failed HTTP requests

[maxlapides]

Summary

When setting up a new Gatsby Wordpress site, I was experiencing a lot of errors that looked like this:

⠄ source and transform nodesThe server response was "401 Unauthorized"
Inner exception message : "You are not currently logged in."

As a new Gatsby user, I had no idea what this meant. It appeared to be a major blocking issue, but turned out to not be a big deal.

My suggestion is to log the paths to the routes that are failing so it's easy for the developer to update excludedRoutes. I ended up hacking the plugin to print the routes so I could figure out what was going on.

Motivation

These errors are very intimidating to new users, and difficult to debug. We can improve the developer experience significantly with a little bit of work on the error logs.

@maxlapides improving developer experience is always a good idea. 🙂
Would you like to work on this and raise a PR?

@kakadiadarpan I unfortunately don't have time to put a lot of thought into this right now, but I just submitted a small PR which I think is a good first step that will make a big difference. Let me know what you think. Thanks!
