Late ktor json plugin installation fails for iOS

[libec]

Installing the JSON plugin to Ktor HttpClient after it's been initialized doesn't seem to take effect on iOS resulting in parsing failure.

Installing the JSON plugin directly in HttpClient's initializer block works fine:

HttpClient {
    install(ContentNegotiation) {
        json(makeJsonNegotiation())
    }
}

Registering HttpClient in Koin and installing JSON plugin later in NetworkClient's init cases parsing failures on iOS

factory<HttpClient> { HttpClient() }
