Title: Erik/tag without message

This fixes makes libgit2 capable of parsing annotated tag objects that lack the optional message/description field.

Previously, libgit2 treated this field as mandatory and raised a `tag_error` on such tags. However, the [message field is optional](http://www.kernel.org/pub/software/scm/git/docs/git-mktag.html)
