We do stuff like this (in the order of execution):

    # ...
    submission_statuses.register('WA', _("Wrong Answer"))
    
    class TestReport(models.Model):
        status = EnumField(submission_statuses)
        # ...
    
    # in different file
    submission_statuses.register('MCE', _("Message Count Exceeded"))


Because of the way EnumField snapshots the registry at construction time,
TestReport.get_status_display will not be aware of MCE's display name.

As a result, Zeus statuses (MCE and MSE) display as "MCE"/"MSE" instead of their full name in the tests table on the submission report page.

Moreover, in the header of submission report page, and on the my submissions page, all statuses (except 'OK', 'ERR' and '?', as those are defined in contests/models.py) show as their acronym (eg. "WA") instead of their full name (i.e. "Wrong Answer")

This may have something to do with SIO-1600
