Bug 35133: Don't lazily define accessor methods when invoked through SUPER

To test:
  1) Apply Bug 32476
  2) Run tests in t/db_dependent/Patrons.t
  3) This should produce multiple "Subroutine Koha::Patron::SUPER::dateexpiry redefined at ..." warnings
  4) Apply patch
  5) Run tests in t/db_dependent/Patrons.t again
  6) The warnings in 3) should now no longer appear
