Bug#17142 Crash if create with encoded name

upgrade.result, upgrade.test:
  Adding test case.
table.cc:
  Don't try to open a table with old-formatted name,
  if the table name contains "@" character.
  This is to avoid mixing two different names to each other.
  Thanks Monty for suggesting this fix.
