needed updates to minitest.ipynb

@sbailey

Once desihub/desitarget#543 has been merged, the minitest notebook will require a few key updates:

• select_mock_targets will now only write out targets-dark, targets-bright, truth-dark, and truth-bright files/catalogs, just as for the real data.
• Separate standard-star files (standards-bright and standards-dark) will no longer be written out (they are in the target catalogs themselves, as for the real data).
• Similarly, when joining the various catalogs and building the MTL, only mtl-bright and mtl-dark catalogs will be written.
• Finally, I may be doing something wrong, but --fibstatusfile no longer appears to be an acceptable argument to fiberassign (perhaps as a result of Use a dynamic focalplane model fiberassign#207, which will require you to SVN-up the appropriate checkout of desimodel/data

@sbailey, I've run the minitest up to the point where select_mock_targets needs to be run. Do you have any advice on what modifications to make?

I'm working on some fixes to that desitarget branch for the minitest notebook, but NERSC outage/degraded problems keep getting in the way of testing. I'll keep trying, i.e. you don't need to work on this right now. Thanks.
