[JENKINS-32323] Trigger a Gerrit event manually generate Event CreatedOn is null

Dear all

When i want to manually select a patch set and trigger it, then get message in logger:

Event CreatedOn is null...Gerrit Server might not support attribute eventCreatedOn. Will NOT persist this event and Missed Events will be disabled!

but task is select and it start to building project.

The gerrit trigger plugin can automatically received events and start task to build without error.

Dear all

The gerrit trigger plugin can automatically received events and start task to build without error.

environment

```
Jenkins version: 1.625

gerrit-trigger-plugin: 2.18.3

gerrit version: 2.11.3
```

No files, tests, or entry points are named. Reproduce the manual patch-set trigger with Jenkins 1.625, gerrit-trigger-plugin 2.18.3, and Gerrit 2.11.3, then trace the code producing the “Event CreatedOn is null” warning. Done means the manual trigger behaves correctly without the reported warning while automatic Gerrit events continue to work.
