Make the db and statemachine default is the same
Created by: jvanbaarsen
What does this MR do?
Remove a warning when you run the test suite:
Both MergeRequestDiff and its :state machine have defined a different default for "state". Use only one or the other for defining defaults to avoid unexpected behaviors.
Are there points in the code the reviewer needs to double check? Maybe there was a good reason to have them different. So please wait for travis to finish its build
Why was this MR needed? To remove an annoying warning.
