userid-validation: erase score after trigger

The newer versions of Gerrit seem to send events that include the
"Ok-To-Test=1" score on future comments by Jenkins itself.  This can
cause Jenkins to infinite loop itself by seeing its own "Validated=1"
comment _with_ an "Ok-To-Test=1" inside it.  There isn't much capability
to filter this out in the Jenkins Gerrit Trigger Plugin.  Attempt to
work around it by adding immediately erasing the Jenkins Ok-To-Test
score.
