basicCreateMonitoredItemsTest.js does not manage subscriptionObjectReference correctly (version setup-opc-ua-1.03-compliance-test-tool-v1.03.09-01.00.500-20220807)
subscriptionObjectReference should be used when it is necessary to reuse the an already established session subscription which is necessary if only 1 subscription is available.

The following tests of "Monitor Value Change" conformance unit were supposed to use MonitorBasicSubscription reference but are not due to the issue (another subscription is created): 002, 004, 005, 006, 007, 008
And the following tests of "Monitor Items Deadband Filter" shall use MonitorBasicSubscription to avoid creation of several subscriptions: 001, 002, 003, 004 and 005

By applying the following patches, it is possible to obtain the expected behavior and to avoid use of several subscriptions while it is not necessary and not supported by all profiles.
