[PP-1] Explore adding support for fallback rendering of slots to RenderSafeComponentContainer

Overview

RenderSafeComponentContainer will try to render a single component, which will traverse into its children.
If rendering of the children succeed but rendering of the component itself fails, we do not output the valid children, only an error message.
In theory in the catch block we should be able to attempt to render a generic fallback that still outputs slot children

Proposed resolution

Make RenderSafeComponentContainer borrow the logic from the fallback source component's renderComponent and setSlots methods to attempt to render the child components when rendering of the component itself fails
