Issue STUDIO-2757: Run history 
When in your workspace you have more that one project you use to run several of them. As a result you start getting a history in the run/debug button of the IDE with the last app run. In eclipse when you close a project the apps related to that project get deleted from the button history so as not to confuse the user. In Studio even though you close the project the run history doesn't get clean.
