  Regenerates a new random deviceId for current user. Note: this is not recommended unless you know what you are doing. This can be used in conjunction with setUserId:nil to anonymize users after they log out. With a nil userId and a completely new deviceId, the current user would appear as a brand new user in dashboard.
