[JENKINS-26865] Matrix parent aborts when 'Exclude trivial rebase' set in gerrit-trigger plugin

I have multi-configuration job with two configurations.
It triggered by gerrit trigger with option 'Exclude Trivial Rebase'
When job is triggered by rebased patchset parent job is aborted and there is messages in log:

review.vsphere » CentOS,vsphere appears to be cancelled
review.vsphere » CentOS,vsphere completed with result ABORTED
review.vsphere » Ubuntu,vsphere appears to be cancelled
review.vsphere » Ubuntu,vsphere completed with result ABORTED
Collecting metadata...
Metadata collection done.
Finished: ABORTED

So it seems that gerrit trigger plugin prevents child jobs from running, matrix parent cannot find them, aborts and sets negative vote on patchset.

In this case matrix parent should be cancelled too and vote should be skipped.

Jenkins ver. 1.598<br/>
Matrix project plugin ver. 1.4 <br/>
Gerrit trigger ver. 2.12.0

Reproduce the multi-configuration Jenkins job using the Gerrit trigger's “Exclude Trivial Rebase” option and inspect how the matrix parent handles children that the trigger prevents from running. Done means a rebased patchset cancels the parent cleanly without a negative vote.
