`prepareUserOperationRequest` ignores `middleware` parameter

Lines 477 to 485 in 0ba75d7

	prepareUserOperationRequest: (args, stateOverrides) =>
	prepareUserOperationRequest(
	client,
	{
	...args,
	middleware
	},
	stateOverrides
	),

client.prepareUserOperationRequest accepts a middleware parameter. This is then embedded in args. However, because args is overwritten by the middleware from smartAccountActions({middleware}), this middleware parameter in prepareUserOperationRequest({middleware}) actually does not have an effect.
