As part of Ian Sullivan's demo on using the new coverage system, we picked places lacking in coverage to add coverage to. I chose DataIdContainer in pipe_base/argumentParser.py, which didn't have a test suite dedicated to it, and had a lot of untested exception handling. This ticket is to clean that up.
