build-artifacts-on-demand marks CI +1

Hi all, I have a change [1] that currently fails some jenkins jobs, so it gets -1 from it. After pushing patchset 4 (a mere rebase actually), I ran build-artifacts-on-demand ("ci please build"), and it passed, and set CI +1. Then I rebased again and again got -1 as expected. IMO build-artifacts-on-demand should not set CI +1, it might be misleading for the maintainer to think that all is good when in fact CI failed. [1] https://gerrit.ovirt.org/71590 -- Didi
