Minor bug

Message

Phalcon\Mvc\Micro::handle(): instanceof expects an object instance

When checking finish handler there is no typof test

cphalcon/phalcon/Mvc/Micro.zep

Line 681 in bf9b70c

if finish instanceof MiddlewareInterface {

But for other handler like after there is a typeof === "object"

It's seem the fix was missing with this commit 30379b6#diff-f935028249fa6ba82f53d50fcb058af22c3cec8db674d7b875292bd9b573669d
