ID Deserialization is broken for Vec

[Sytten]

With the changes related to Integer deserialization, it broke the case for Vec<ID> and Option<Vec<ID>

`?` operator cannot convert from `std::string::String` to `std::vec::Vec<std::string::String>`
expected struct `std::vec::Vec<std::string::String>`
   found struct `std::string::String`

= note: `?` operator cannot convert from `std::string::String` to `std::option::Option<std::vec::Vec<std::string::String>>`
   = note: expected enum `std::option::Option<std::vec::Vec<std::string::String>>`
            found struct `std::string::String`
