Inconsistent invocation of @Before (and similar) handlers with http method handlers

[Itzdlg]

Actual behavior (the bug)
A before handler registered using @before and default values, alongside @endpoints, does not get invoked for all paths that a similarly-annotated method handler does.

Expected behavior
All paths that trigger a method handler should trigger the equivalently-registered @before, @BeforeMatched, @after, and @AfterMatched handlers.

        config.router.mount(AnnotatedRouting) { routing ->
            routing.registerEndpoints(
                @Endpoints("/test/{id}")
                object {
                    @Before
                    fun before(ctx: Context, @Param id: UUID) {
                        ctx.header("before", id.toString())
                    }

                    @Get
                    fun get(ctx: Context, @Param id: UUID) {
                        ctx.header("get", id.toString())

                        ctx.header("get", id.toString())
                    }
                }
            )
        }

        config.validation.register(UUID::class.java, UUID::fromString)
    }.start(8080)

    val id = UUID.randomUUID()
    val testPaths = setOf(
        "http://localhost:8080/test/$id",
        "http://localhost:8080/test/$id/",
        "http://localhost:8080/test/$id/specific",
    )

    for (path in testPaths) {
        println("Testing $path")

        val response = request("GET", path).asEmpty()
        assertThat(response.headers.getFirst("before")).isEqualTo(id.toString())
        assertThat(response.headers.getFirst("get")).isEqualTo(id.toString())
    }
}
