(maint) Reword debug message
When puppet autorequired a resource, its debug message used to say:
Autorequiring File[/Users/josh/.puppet]
Commit b864bfbcd for PUP-3331 added the ability to define autobefore,
autonotify, and autosubscribe relationships, similar to autorequire. In
the process the debug message changed to support these other types of
relationships:
Forming automation relationship of type <type> with File[/Users/josh/.puppet]
This commit changes the message to be more concise:
Adding auto<type> relationship with File[/Users/josh/.puppet]
