- Disable callback refresh_member_authorized_projects when importing
   a group or project due to the fact that it can cause import to take
   significantly longer. Refresh of authorizations is not needed to be
   done during the import for each individual member
 - Enqueue async AuthorizedProjectUpdate::ProjectRecalculateWorker
   instead at the end when import is finished in the after import hook.
   This ensures authorizations are updated still updated, but it's done
   in scope of 1 sidekiq job
