False positive on enums with 2.0.6

[garak]

After upgrading from 2.0.5 to 2.0.6, all my enum fields raise doctrine.enumType errors:

Property App\Foo::$bar type mapping mismatch: backing type string of enum App\Foo\Value does not match database type string.

See the discussion here #678 (comment), possibly contribute a fix 😊
