[FIX] payment: wire transfer redirection

When sequentially paying multiple SO with wire transfer, the user was
always redirected to the first paid SO.

This commit fixes this issue by redirecting to the most recent one.

Technical choice:

payment_transaction rows are ordered by id desc so we can trust the
first one will be the most recent on the client side (in the scope of
this diff).
