Fix XML UnicodeEncode serialization error

The generic Nova XMLSerializer code will currently attempt
to cast to str the value for all leaf nodes. This patch
ensures that no attempt is made to convert unicode which
can cause a UnicodeEncode error. We don't need to convert
unicode for XML text and regardless we encode to UTF-8 at
a later point.
