Fix for issue #2765 relative to unstable trafficshaping test procedure
Motivation:
The test procedure is unstable due to not enough precise timestamping
during the check.
Modifications:
Reducing the test cases and cibling "stable" test ("timestamp-able")
bring more stability to the tests.
Result:
Tests for TrafficShapingHandler seem more stable (whatever using JVM 6,
7 or 8).
