General Improvements on relation to Experience handling when turn on/off

Small improvements related to Flow experience validation and handling:

• CurrentZoneLoader#current_zone will force refreshing the zone if the zone stored in the session is not active. This will force orders to use a new active zone or eventually default to International Zone.
• OrderUpdater will allow updating orders that are associated to experiences that are it archiving status. This will allow avoiding issues for users that were completing the checkout when the experience started being archived.
