8251843: jfr/tool/TestPrintJSON.java fails intermittently

[egahlin]

The 'jfr' tool can print events in JSON and XML and the result is verified by reading the same file using the jdk.jfr.consumer API. The method RecordedEvent::getEndTime() exposes timestamps with nano-precision (java.time.Instant), while the tool sorts them according to ticks. It is believed that events with different ticks timestamp in some circumstances may get the same nano-precision timestamp. This leads to events not arriving in the same order and the test fails.

Fix is to sort events in the test by ticks as well
