[V122-specific] Remove double-swap intermediate outbound event

[V122-specific]

Intended to close #1690 (closed)
'Why are double-swap THOR.RUNE outbound events emitted?',
effectively reverting !963 (merged)
'484-issue emit an outbound event for double swap';
alternatively closable by a convincing explanation of the double-swap intermediate outbound event being worthwhile.
