Description

When you're importing expired subscriptions with their "End date", this date is automatically replaced by the current date (the importation time).

Steps to replicate

1. Make sure that you have an expired subscription on your site (if not, create one and change its "end date" [_schedule_end] from the database to have an old date)
2. Export this subscription
3. Delete the subscription
4. Import it and check if its 'End date' has the same date as the original subscription

Expected results

After importing the subscription, its "End date" should be the same date that was specified in the CSV.

Result

The "End date" of the imported subscription is replaced with the current date.
