MDC events should create omegascans
Currently, submitting an MDC calls the detchar.make_omegascan()
task, which looks for data and then makes an omegascan with that data. MDCs, most of the time, won't point at real data, so the omegascan doesn't actually get made and instead a "omegascan failed" placeholder image is created and uploaded to the superevent page.
Instead, to more accurately replicate what happens when an event is uploaded, make_omegascan
should do something like take a kwarg indicating that the event is an MDC and subsequently make an omegascan of the saved test data that's part of the package, instead of digging through the filesystem looking for nonexistent data.
