Monitoring summary screen, Learner and teacher export portfolio and
Learner view only report screen generation logic have been modified to work with the recent request scope changes to learner module.
Right now all these modules are functional as beforwe, however monitoring and export portfolio still depends
on session scope to hold certain data.
The focus was to make learner module truly request scope based and all these other modules to work normally for the time being. These other modules could be
converted to request scope if that is needed as well.
