Fixed the problem #157 point 2: now a package editing with no attributes to be showed, doesn't show the 'select services' section, and where there are not pre-checked attributes, all attributes are showed as mainly not under 'show more' link. Only if there is not pre-checked, preserving the previous logic for that cases.
