Possible fix error with multiple uses of enum (#1473)

When an enum is exists in the type cache and isn't String, @DbArray
fails. This includes a test that should fail everywhere (order of
reading fields isn't guaranteed afaik and the column needs to be read
before the @DbArray for the test to fail).
