E0401: A route is declared twice

Two handlers declare the same method and path, so a request can't tell them apart. Both places are shown. Reported at boot, and by vukavet.

Wrong

@web.Get("/pets")
func ListPets(store *PetStore) []Pet { … }

@web.Get("/pets")
func AdminPets(store *PetStore) []Pet { … }

func init() {
	web.Routes.Get("/pets", ListPets)
	web.Routes.Get("/pets", AdminPets)
}

Right

@web.Get("/pets")
func ListPets(store *PetStore) []Pet { … }

@web.Get("/admin/pets")
func AdminPets(store *PetStore) []Pet { … }

func init() {
	web.Routes.Get("/pets", ListPets)
	web.Routes.Get("/admin/pets", AdminPets)
}
