[FIX] mass_mailing: fix tracking link creation in mass mailing

When using only mass mailing two issues arise when trying to send mass
mailings containing links

 * a link.tracker is created for each link to shorten; however rights are
   given currently only in website_links for website designers and not to
   marketing users that use mass mailing. This commit adds the rights for
   link.tracker model to those people;
 * a link.tracker.code is created to hold the shortened versions of the
   links. As it is a technical model it is now done as superuser as rights
   on link.tracked model has already been granted and adding rights on such
   a technical model is not necessary;

A test is added that checks what is done with links when sending mass
mailings. It helped spotting the hereabove issue.
