[FIX] account: instant payment post process

When register a payment, and choosing a payment acquired.

Before this commit, the payment post process had to wait until a cron
run (every 10 minutes).

Now, The post process is executed instantly after the payment, if the
payment is not yet done, the post process will be executed in the next
cron run.
