Build error with tiberius without serde

[krojew]

When building refinery-core with tiberius feature but without serde, there a build error at config.rs:274:7:

#[derive(Debug)]
#[cfg_attr(feature = "serde", derive(serde::Serialize, serde::Deserialize))]
struct Main {
    db_type: ConfigDbType,
    db_path: Option<PathBuf>,
    db_host: Option<String>,
    db_port: Option<String>,
    db_user: Option<String>,
    db_pass: Option<String>,
    db_name: Option<String>,
    #[cfg(feature = "tiberius-config")]
    #[serde(default)]
    trust_cert: bool,
}

#[serde(default)] is not guarded against not having serde feature, thus resulting in "cannot find attribute serde in this scope".

Hi, this is indeed a bug, but it shouldn't be reproducible as one shouldn't build refinery-core, specially with tiberius-config which is a feature only used by refinery-cli, may I ask why are you doing it?

If I recall correctly, there was a case for it in https://github.com/krojew/springtime/tree/master/springtime-migrate-refinery, but can't remember exactly what.
