t5505-remote.sh: check the behavior without a subcommand
'git remote' without a subcommand defaults to listing all remotes and
doesn't accept any arguments except the '-v|--verbose' option.
We are about to teach parse-options to handle subcommands, and update
'git remote' to make use of that new feature. So let's add some tests
to make sure that the upcoming changes don't inadvertently change the
behavior in these cases.
