Title: Standardize getter return values for empty sets. Fixes #11962

The ticket: http://bugs.jquery.com/ticket/11962

`.html()`, `.offset()`, and `.position()` now return `undefined` instead of `null` when called on an empty set.
Tests included (though I'm not sure if they are necessary here)

p.s.: grunt's compare_size says: `33162 (-2) dist/jquery.min.js.gz`
