Subject: [PATCH] Update WebApiFactory.cs (#153)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This could fix the ImplicitGrantAuth for http paths without breaking anything. ´TrimEnd` is there for when there is no path (the builder will add a `/` which will make the callback url invalid otherwise.
