Subject: [PATCH] Check if project_config_ref is defined before using it

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.
