[Rust] update_registration_flow error handling

まず、すでに登録されているメールアドレスに対する update_registration_flow と ResponseContent の処理を追跡します。ErrorBrowserLocationChangeRequired がどのように構築されるかを調べ、その entity と response statuscode を比較します。statuscode が空の場合の動作に一貫性があり、再現時に redirect_browser_to が None として返されなくなれば完了です。

Describe the bug

UpdateRegistrationFlow ResponseContent.entity returns a different empty status compared to ResponseContent.statuscode. ErrorBrowserLocationChangeRequired always returns None:

pub struct ResponseContent<T> {
    pub status: [StatusCode](https://docs.rs/http/0.2.11/http/status/struct.StatusCode.html),
    pub content: [String](https://doc.rust-lang.org/nightly/alloc/string/struct.String.html),
    pub entity: [Option](https://doc.rust-lang.org/nightly/core/option/enum.Option.html)<T>,
}

ResponseContent {
