Asynchronous EventListeners are being called multiple times when not needed.

Some Xray actions are triggering asynchronous events multiple times. In long-running tasks like the pre-calculation of Requirement Status, this may lead to unnecessary operations occupying a large number of available threads.

Taking the TestSetsCustomField.java as an example, it'll trigger the pre-calculation:

• 1 T + N TS times;
• N (1 T + 1 TS) times;

where N is the number of Test Sets associated with the Test.

In sum:

• the requirements dependant of that specific Test are pre-calculated N + 1 times.
• the requirements dependant of the linked Test Sets are pre-calculated N + N times.
• Xray will be using 1 + N threads.

All operations that trigger this kind of events should be analyzed.
