[FIX] payment_payulatam: cancel transaction can be set to done

Steps to reproduce:
A) Share a payment link and pay with PayU Latam (you'll be redirected
to their checkout page)
B) Make sure that your first payment attempt with Pay U Latam fails
(they provide the cards info to simulate successful and failed
payments)
C) After the first failed attempt, stay on the same checkout page and
do a second attempt (this time a successful attempt)
D) Click on 'Go back to the website of the shop' (still on the
checkout page).

Current behavior:
Odoo will show 'Your payment has been canceled'

Expected behvavior:
Odoo will show 'Your payment has been confirmed'

Explanation:
After the first payment failure payulatam calls the webhook to cancel the
transaction but after it lets the user the possibilty to retry the same
payment again and if the payment succeed it calls the webhook again to
confirm the transaction but it can not as the transaction is already in
a canceled state. To prevent this issue we allow the payulatam webhook
to set the transaction from canceled to done by adding canceled in the
allowed states of _set_done()
