Can't save empty array

[MihaelIsaev]

I have a Fluent model

final class Experiment: Content {
    var id: UUID?
    var tags: [String]?
}

When I'm trying to save it

Experiment(tags: ["test"]).save(on: conn) // works
Experiment(tags: nil).save(on: conn) // works
Experiment(tags: []).save(on: conn) // throws error

error is

⚠️ [PostgreSQLError.server.error.array_recv: wrong element type]

It worked before update to the latest Fluent/PostgreSQL release with a lot of changes.
So it seems like a bug, cause saving empty array is not a crime 🤔

Fixed in #79, thanks for reporting!
