Social: Fix empty state mix up when all connections are removed after attaching an image. (#46351)

* Ensure that the form is shown only when there are connections

* Remove the unnecessary wrapper logic

Wrapper is needed only if we show the social UI but we don't because we hide it completely when not needed.

* Decouple EmptyState component from user connection logic

* Further simplify PublicizeForm component

* Add changelog
