[FIX] payment: provide missing return_url in values

Render from payment//payment_acquirer.py promises:
All templates will receive:
    'feedback_url', 'return_url', 'cancel_url', 'error_url'
However they are all in -> FIXME.
After 6 years in FIXME, this promise is still a lie.

It is unfortunate since the Adyen payment provider requires 'return_url' to work.
Before, this function was called by _get_shop_payment_values,
which provided a value for it.
We copy the value that was given there directly as a default in render,
so that it doesn't crash no matter what method calls it.
