Fix export all different question types

[microstudi]

• Exporting a pdf or csv does not work for questions with logic. All types of questions should be exported. We need a full check (including separators and matrix questions as well).

• Additionally, the export does not work if some questions does not have the "order" attribute defined, in here is fixed (just a .to_i added):

• Also, it seems that the QuestionnaireAnswerPresenter does not have access to the current_organization method when running translated_attribute, here is a simple fix:

• Zip compressed archive should not have folders inside,
  

• PDF export should respect line breaks (\n), otherwise long texts are too compact.
