select() with nested keys issue

[flovilmart]

When using the select() method with nested keys (i.e.: key1.key2) key1 needs to be included automatically.

ex:

let query = new Parse.Query("MyObject");
query.select("key.key2");
// does not work

let query = new Parse.Query("MyObject");
query.include("key");
query.select("key.key2");
// works!
