Spread arguments in new call don't work in TS 1.4

[yukulele]

Array literal (rest parameter) don't seem to work with constructor

example:

let a = [1, 2, ...arr, 4, 5]; //works
Math.max(...arr); //works
myFunction(...arr); //works
new myClass(...arr); //error

Should work with ES5 target, see #2369
