satellite/console: Update STORJ token upgrade logic

During free trial implementation, one case was missed for upgrades via
token - the limits are upgraded and user is upgraded to pro, but the
freeze event is not removed. This change ensures that the trial
expiration freeze is removed during token upgrade.
