Can not insert with mut reference using values

[xinghun92]

This code can not compile.

fn test_insert_mut_users(users: &mut [::NewUser]) {
    let conn = ::establish_connection();
    ::diesel::replace_into(::users::table).values(users).execute(&conn).unwrap();
}

#[test]
fn test_insert_mut() {
    let mut users = ::create_new_users(10);
    test_insert_mut_users(&mut users);
}

The error is

::diesel::replace_into(::users::table).values(users).execute(&conn).unwrap();
    |                                                ^^^^^^ the trait `diesel::Insertable<__diesel_infer_schema::infer_users::users::table>` is not implemented for `&mut [NewUser<'_>]`

And insert _or_replace works well

fn test_insert_mut_users(users: &mut [::NewUser]) {
    let conn = ::establish_connection();
    ::diesel::insert_or_replace(users).into(::users::table).execute(&conn).unwrap();
}

And I must uselet users = Vec::from(users) before insert, I think the ergonomics is bad.

Changing users to &*users will fix it.
