Wrong error being returned

[gouthamve]

Hi, when we have both /route and /route/:something. Navigating to /route/ is throwing method not allowed which is wrong.

It should either redirect to /route or show not found.

Code to reproduce:

package main

import (
    "net/http"

    "github.com/labstack/echo"
    mw "github.com/labstack/echo/middleware"
    "github.com/rs/cors"
)

func main() {

    // CORS Middleware
    corsMw := cors.New(cors.Options{
        AllowedOrigins: []string{"*"},
    }).Handler

    // Echo instance
    e := echo.New()

    // Middleware
    e.Use(mw.Logger())
    e.Use(mw.Recover())
    e.Use(corsMw)
    // Routes
    e.Get("/stages/:stage", hello)
    e.Get("/stages", hello)

    // Start server
    e.Run(":3001")
}

func hello(c *echo.Context) error {
    return c.String(http.StatusOK, "Hello, World!\n")
}

Going to /stages and /stages/hello is showing Hello, World! but going to /stages/ is showing Method Not Allowed and throwing the following in the console

ERROR|echo|Method Not Allowed
INFO|echo|::1 GET /stages/ 405 97.403µs 19
