run_tests_on_string inconsistent return type/value

[ahamid]

run_tests_on_string is not returning a value (returning undefined) on code with no type annotations:

197     if(types.length > 0){
198       var suite = [];
199       for(var i = 0; i < types.length; i++) {
200         var base = this.addTest(types[i], null, redefine);
201         suite.push(base);
202       }
203       return TypedJS.go(suite, redefine);
204     }
205   }
