This checks if the $::project_config_ref fact is defined before accessing it. Puppet 4 seems to care about his more than puppet 3 so we are only just notcing this now. Note that this fix relies on puppet boolean operator 'and' short circuiting which I'm not entirely sure if it does yet. Change-Id: I2b89ac146609f9c3b22c05814b85c646f74b393a
