Emit whoami JSON as an array in every case

whoami --format json returned a bare object for an explicit profile or
environment credentials but an array for the all-profiles listing, so
scripts had to branch on the invocation. Route every path through
WhoamiList so the JSON output is always an array, consistent with the
list and search commands.
