t3301-notes.sh: check that default operation mode doesn't take arguments

'git notes' without a subcommand defaults to listing all notes and
doesn't accept any arguments.

We are about to teach parse-options to handle subcommands, and update
'git notes' to make use of that new feature.  So let's add a test to
make sure that the upcoming changes don't inadvertenly change the
behavior in this corner case.
