[PATCH] RecipeResults.py: Added __get_state__ to DeviceMethodCallResult

From: Perry Gagne <pgagne(a)redhat.com&gt;

Had to exclude args since they might contain Device objects (ex. when creating a team
device)

I have a couple ideas for a more thorough approch here, but whated to commit this right
away to unblock
testing since it might cause beaker jobs to fail.
