Due to could not call pipeline job in multijob, I upgrade MultiJob plugin from 1.29 to 1.32 by following the advise of #152

After upgrade complete, I found that the status display in multiple job is not correct. img1 is the screenshot before upgrade, img2 is the sceenshot after upgrade.

After upgrade, there are status circle on phase name. And the status always show grey after the job is executed succeed.
