Description: Restore Mockery @instances after deliberately nil'ing it
 The MockeryNeverSetupTest deliberately sets @instances to nil to check
 that teardown raises NotInitializedError. When the Minitest integration
 is loaded (giving us per-test verification), its before_teardown hook
 runs after the test method and crashes on the nil @instances.
 .
 Restore the original value after the assertion so the hook can run
 cleanly (defaulting to [] for an empty mockery if it was nil).
