LDEV-1265: If you deleted a transition and then redrew it, it triggered a unique key exception. Now the code reuses transitions based on either the UIID or the to/from activity UIIDs so it doesn't trigger the exception.
integrationService.getExtCourseClassMap creates the ext_course_class_map, and the matching lams org, for the 3rd party course; since the org is now a course (with workspace folder) instead of class, it's nice to have the folder appear when 3rd party users browse list of learning designs.
LDEV-1134: Fixed the View Branches screen for tool output based branching - I can't list the users based on groups as they aren't in groups (and I can't put them in groups as the groups have to be linked to the condition and if the user goes to the default branch there is no condition). So for tool output based branching I have to find the users via their progress records.
