Teams for WooCommerce Memberships

Expired team members cannot be removed from a team. But when renewing a team, the expired members are still counted in the seat count.

This causes a functional flaw. Consider this scenario:

A team is created with 10 seats. All 10 seats are allocated. After a period of time, all 10 memberships expire and so does the team. Now if the team owner wishes to renew the team but just with 5 seats, they cannot do so. The renewal forces them to select 10 seats, and they cannot remove the expired members to reduce this seat count.

The solution is to allow expired members to be removed by the team owner and reduce the seat count when they are removed.
