    Rackspace database resource output is null

    current implementation of rackspace database resource
    _resolve_attribute method assumes that clouddatabase object's
    hostname and href are set to correct values and just returns
    them, but that assumption is not correct. With this change,
    hostname/href is retrived if it was not set already.

    Fixes Bug #1204601
