Change return for errdefs.getImplementer()
The types defined in the errdefs package do not
satisfy the `error` interface, because they do not
implement `Error()`.

Instead of returning the matched interface, return
the original error.

When matching _multiple_ interfaces/types, Golang doesn't complain:

    func getImplementer(err error) error {
        switch e := err.(type) {
        case
            ErrNotFound,
            ErrInvalidParameter:
            return e
        default:
            return err
        }
    }

But matching a single interface/type:

    func getImplementer(err error) error {
        switch e := err.(type) {
        case
            ErrNotFound:
            return e
        default:
            return err
        }
    }

Produces an error:

    cannot use e (type ErrNotFound) as type error in return argument: ErrNotFound does not implement error (missing Error method)

Return the original `err` instead of the matched interface/type instead.

Also added some additional tests
