[TIMOB-1794] Android: Mixed type arrays assigned to proxies throw ClassCast exception

Description

var win = Titanium.UI.createWindow();
var foo = ["foo", "bar",999];
 
// uncommenting this fixes it, because its no longer mixed type
// foo = ["foo", "bar","999"];
// this also works
// foo = [111,222,3333];
 
// exception doesnt happen until the array is assigned to a proxy object
win.foo = foo;
alert(win.foo);
win.open();

   As discussed with Don, the following code also produces an exception in 1.4.3 (21Nov) but not in 1.5.X (17Dec).

      var window = Titanium.UI.createWindow({  
          backgroundColor:'red'
      });
      
      var view = Titanium.UI.createView({
          backgroundColor:"blue"
      });
      
      var x = [ 1,2,3,4,5,6 ];
      view.myArray = x;
      window.add(view);
      window.open();
      
      function isArray(obj) {
         if (obj.constructor.toString().indexOf("Array") == -1)
            return false;
         else
            return true;
      }
      
      Ti.API.info("x type isArray = "+isArray(x));
      Ti.API.info("view.myArray[3] = "+view.myArray[3]);
      Ti.API.info("view.myArray type = "+typeof(view.myArray));
      Ti.API.info("view.myArray type isArray = "+isArray(view.myArray));  //this causes the exception

   Not sure why this is still open if it's in 1.5.1 please test and close if not valid.

   (from [9e588f2c63514f614a78c32f37c14071a2a2d1a4]) the kroll invocation scope needs to pull from the current thread's ti context top level scope instead of the "start" which is essentially the
   same as the "thisObject". added a kroll test, this fixes "constructor"
   for Array and other types [#1794 state:fixed-in-qa]

   Verified crash is no longer occurring with test case from Hal.
