Quoted promises don't work with Promise static methods

[jcubic]

Example:

(Promise.all (vector '>(wait 1000 10) '>(wait 1000 10)))
;; ==> #(#<js-promise (pending)> #<js-promise (pending)>)

This is because right now quoted promise don't work like promises anymore to fix #153
Blocking of promise should work like boxing and unboxing. So JavaScript functions and methods get promise like object.

this works:

(let ((x (vector '>(wait 1000 10) '>(wait 1000 10))))
  (--> x (map (lambda (x) (set-obj! x 'then))))
  (Promise.all x))
