During hotloading the `ScriptRequest` was constructed from a
`JSContext*`. That requires that already an other `ScriptRequest` is
active. Which isn't always the case.
Now The `ScriptRequest` is constructed from a `ScriptInterface&`.
Storing a `ScriptInterface&` in the `ModuleLoader::Result` allows to
remove the `m_Result` as it is retrieved from the `ScriptInterface`.
