Closes issue #133 [GUI is unable to delete a project if the project folder has already been deleted]
- ensure callback is called for fail scenarios when deleting/creating projects
- show alert to user when project was already deleted from FS outside of gui tool
- remove projects from model if they don't exist and on errors [projectList.js]
- only call error callback if one was provided [server.js]
- code cleanup
