superproject: Log argv parameter of syncstate as 'data-json'.

Fixed: "we need to make a special case for logging the argv; it
should probably be a "data-json" event so that we log this directly as
an array rather than an encoded string.

Tested:
$ repo_dev sync

Verified event logged for argv is "data-json".

$./run_tests
