Title: Don't include a hyperlink if href attribute is nil

Hi!

In the context of https://github.com/apotonick/representable/pull/2 I noticed a small inconsistency. Properties with nil values don't get included but links with a nil href attribute stay in the representation.
A future ```:include_nil``` option could affect this behavior, too.

Note: This pull request only illustrates the problem and shouldn't be merged as it is.
