Automatic builds created due to autostart, autostop, or dormancy should not be created if there are no provisioners available with matching tags.

Otherwise we get into a fight with the new job reaper code and we will keep churning out new jobs (especially for dormancy, which will cause new jobs every 30 minutes).
