v4.12.6 - fix websocketOperations: all
Fixes a couple of bugs related to websocketOperations: 'all'
--websocket-operationsCLI flag was previously ignored- When issuing queries/mutations over websockets,
singleStatement: truewas set incorrectly (this should be set only for subscriptions), resulting in performance costs and errors when issuing mutations that use savepoints (which should be all mutations).
