Subscription MonitoredItem with IndexRange: notification on value change not generated
Description
For MonitoredItems with a defined IndexRange, the first notification after CreateMonitoredItem is triggered but no notification is triggered in case of value change for the MonitoredItems.
Analysis
An incorrect return value evaluation was done in the notification generation code in case of MonitoredItems with an IndexRange making it fail on each value change. This behavior was introduced by commit 96028faf (08/02/2019).
