Title: return nil if no expires on cookie (fixes #203)

Hey,

not sure if I updated correct place in changelog (my first contribution).
This fixes https://github.com/jonleighton/poltergeist/issues/203
When `expires` is not set on cookie and it is called, currently error appears. This fix returns nil instead.
