Do more to deal with Resource/Routes paths eating each other

[Ghnuberath]

For example, registering a Resource with super('/') and another with super('/test') could result in the former's get (ctx) preventing the latter's getAll (ctx) from functioning.
Requiring Routes and Resources in descending order of number of path components might address this.

Courtesy of @ggayowsky, this bug is also related, and a complete pain when two routes match the same request. The current behaviour is that both routes are run, and a 500 is produced due to internal Ravel assumptions that certain middleware (in particuar, Rest.respond only runs once per request).

Unfortunately, there's been no real activity on this issue for a long time, either in koa-router or its official fork @koa/router.
