 - Drop the newly created user user1@localhost
 - Cleanup testcase


mysql-test/r/ndb_bug26793.result:
  Update test result
mysql-test/t/ndb_bug26793.test:
  - Remove the drop/restore of anonymous users - there are no such users
  by default anymore(if there were, they would probably be in mysql.user)

  - Drop user1@localhost as part of cleanup
