[tor-commits] [stem/master] Test failures presented invalid '--test' arguments

    Test failures presented invalid '--test' arguments
    
    Our integ tests are rightfully failing right now, but the message presented at
    the end is incorrect...
    
      You can re-run just these tests with:
    
        ./run_tests.py --all --target ONLINE --test test.integ.manual
        ./run_tests.py --all --target ONLINE --test test.integ.descriptor.collector
    
    The trouble is that to reduce verbosity I dropped the need for module prefixes
    (so you can run '--test descriptor.collector' instead), but...
    
      1. The above message didn't account for that.
    
      2. We were bugged in that we no longer worked with full module names, so
         running the command we advised didn't work.
    
    Both accepting full module names and now presenting short test module names.
