d3 install --freeze doesn't freeze if the edition is already installed

[jminor]

If you run d3 install something-123-1 --freeze and that edition is not installed yet, then the right thing happens. However, if that edition is already installed, the command exits without freezing. Having the same edition already installed should not be considered an error.

Also, related, if you run d3 install something-123-1 --freeze --force but 123-2 is already installed, then it freezes 123-2 without installing 123-1.
