`taskcluster signìn` integration doesn't extend expiration

[jonasfj]

If the .../cli client exists and is expired, it just rotates the accessToken and that's it... The client I get back is still expired..

Note: We do set deleteOnExpiration, but I'm pretty sure that taskcluster-auth still waits a few days after expiration before deleting clients.

@helfi92 just wrote code to also update the expiration date. I don't know if that's landed yet, given the change freeze?
