Bug: deserialization for enums with #[serde(flatten)] is not working

[josecelano]

I think these two failing tests could be the same problem because they both use #[serde(flatten)] for an enum field.

• cargo test ser_de_flattened_enum -- --nocapture
• cargo test ser_de_flattened_adjacently_tagged_enum -- --nocapture
