Streamline 1.0 fails on CS comprehension idioms

[bjouhier]

See #298

Repro:

nodes = (@createTestNode suite, _ for i in [0...numNodes])

And here's the JS that compiles to:

nodes = (function() {
  var j, ref, results1;
  results1 = [];
  for (i = j = 0, ref = numNodes; 0 <= ref ? j < ref : j > ref; i = 0 <= ref ? ++j : --j) {
    results1.push(this.createTestNode(suite, _));
  }
  return results1;
}).call(_this);

@aseemk
Streamline does not handle the idiom with _this, just this. Should be easy to fix.

Thanks @bjouhier!

@aseemk You're welcome 😄

I'm going to stop here for the day. I'll fix #301 and #297 tomorrow and I will republish to NPM. I'll look at the other ones a bit later.
