CLI fails on files with no type annotations

[ahamid]

// define a namespace
if (typeof MyNameSpace == "undefined") {
  var MyNameSpace = this.MyNameSpace = {};
}

Run without extract:

typedjs namespace.js

namespace.js: ✘
null
Done.

Due to internal error:

[TypeError: Cannot read property '0' of undefined]

Because TypedJS run_tests_on_string function does not return results array when there are no types to check; returns undefined/non return value instead. Probabaly a TypedJS bug.

trivial patch coming
