migrate.versioning.shell.main() test for argv

[GoogleCodeExporter]

The main() function currently uses the following code to switch between the 
argv passed versus sys.argv:

    argv = argv or list(sys.argv[1:])

This should be:

    argv = argv if argv is not None else list(sys.argv[1:])

So that when an empty list is passed (argv=[]), it will consider no command to 
have been selected, as opposed to whatever might be in sys.argv.

I ran across this while integrating the migrate command into a parent parser.
