When attempting to use the PatreonAPI#fetchCampaigns, I am getting the following response:

<title>Redirecting...</title>
<h1>Redirecting...</h1>
<p>You should be redirected automatically to target URL: <a href="http://www.patreon.com/oauth2/api/current_user/campaigns?include=rewards%2Ccreator%2Cgoals">http://www.patreon.com/oauth2/api/current_user/campaigns?include=rewards%2Ccreator%2Cgoals</a>.  If not click the link.

The library is initially trying to hit the url https://www.patreon.com/api/oauth2/api//current_user/campaigns?include=rewards%2Ccreator%2Cgoals. I haven't made changes to my client code in almost 3 years, so I'm assuming there was an API change?
