Path returns the path that the Goji router uses to perform the PathPrefix

path and an empty path, Goji will automatically extract a path from the request

By convention, paths are stored in their escaped form (i.e., the value returned
by net/url.URL.EscapedPath, and not URL.Path) to ensure that Patterns have as
much discretion as possible (e.g., to behave differently for '/' and '%2f').
