Description:
------------
calling closure when providing it as an arg from the args array provided as the 
second parameter for the invokeArgs method from \ReflectionMethod class

Test script:
---------------
method is:
public function simpleTest($a, callable $b, array $c)
    {
        return (int) call_user_func_array($b, $c) + $a;
    }

$params is:
array (size=3)
  0 => int 2
  1 => 
    object(Closure)[95]
  2 => 
    array (size=1)
      0 => int 2

and calling:
 $this->refl->invokeArgs(new Blablabla, $params);

will generate the bug

Expected result:
----------------
method returning value

Actual result:
--------------
Error: Argument 1 passed to {closure}() must be of the type array, integer given

In fact instead or the array is provided the "int 2"
