Return stripped m.space.child events via the space summary. (#10760)
The full event content cannot be trusted from this API (as no auth chain, etc.) is processed over federation. Returning the full event content was a bug as MSC2946 specifies that only the stripped state should be returned. This also avoids calculating aggregations / annotations which go unused.
