DELETE calls on Config API produce strange log messages

[rupakg]

I accidentally performed some cleanup and called DELETE API calls twice, and I get some strange log messages:

DEBUG	Function deleted.	{"functionId": "createUser"}
DEBUG	Function deleted.	{"functionId": "getUser"}
DEBUG	Function deleted.	{"functionId": "welcomeUser"}
DEBUG	Subscription deleted.	{"event": "userCreated", "functionId": "welcomeUser"}

@rupakg thanks for testing! Looking into it right now.
