Summary:
`renderApplication` receives the root component that we need to render and an optional wrapper component. There are cases where we want to use the initial props passed to the root component in the wrapper component as well (e.g.: to provide a specific context to the root component), so this adds modifies `AppContainer` to accept the initial props and inject them into the wrapper component.
Changelog: [General] [Added] - Modified `renderApplication` to forward `initialProps` to `WrapperComponent`
