Description of problem:

Logs in "Instance Log" field in "Instance Details" panel are ordered by date. But if those logs (NodeInstanceLog) have the same timestamp, they are displayed in random order. It could be solved by 'ORDER BY log.date DESC, log.id DESC'.

Version-Release number of selected component (if applicable):

6.0.0 ER7

Steps to Reproduce:

1. Create simple bpmn process(StartNode->ScriptTask->EndNode)
2. Build and deploy package.
3. Go to "Process Management"-->"Process Definitions" and start process instance
4. Check the "Instance Log" in "Instance Details" panel.

Actual results:

The same timestamp logs are displayed in random order.

Expected results:

The same timestamp logs are ordered by id (DESC).
