[Review] Request from 'KalabiYau' @ 'SUSE/connect/review_140602_add_status_model'

Please review the following changes:
  * d706f06 Implement status key
  * 39af21f Remove commented debugger
  * 7c1d52d Added specs for new functionality

in fact it say nothing new then test above. I do not see any special nil handling in code. it is simple `nil != '12'`
