cli: get settings from repo or workspace

This ensures that WorkspaceCommandHelper created for initialized/cloned repo
refers to the settings object for that repo, not the settings loaded for the
cwd repo.

I also removed WorkspaceCommandEnvironment::settings() because it doesn't own
a workspace object. It's implementation detail that the env object holds a
copy of workspace.settings(), and the caller should be accessible to the
workspace object.
