fix issue #338: Make devPhase part of groupName

This small change intends to fix #338. 

What is unclear to me now is why I have two failures in LoadBalancerControllerTests.groovy:

1)
Cannot invoke method getBean() on null object
java.lang.NullPointerException: Cannot invoke method getBean() on null object
	at com.netflix.asgard.LoadBalancerController$_closure5.doCall(LoadBalancerController.groovy:127)
	at com.netflix.asgard.LoadBalancerControllerTests.testSaveWithoutMostParams(LoadBalancerControllerTests.groovy:62)


2)
Cannot invoke method getBean() on null object
java.lang.NullPointerException: Cannot invoke method getBean() on null object
	at com.netflix.asgard.LoadBalancerController$_closure5.doCall(LoadBalancerController.groovy:157)
	at com.netflix.asgard.LoadBalancerControllerTests.testSaveSuccessfully(LoadBalancerControllerTests.groovy:88)


Interestingly, the failure only happens when I run all tests (grails test-app) but not when I run only the LoadBalancerCrontrollerTests, so it looks like there may be an order-dependency somewhere in the tests?
