HOLI-6748: fix update space room and child avatar/name

As a developer listening to events emitted by the Matrix server, I want to receive events in the corresponding room. For example, when the Okuna Space name changes, I want that event to be reflected in the Matrix Space. Currently, we respect the Holi functionality of 1 Matrix space shild, reflecting the metadata of the parent Matrix Space room. This MR fixes the issue of setting name and avatar for both a Matrix space an its child.
