[FIX] payment: Acquired deployed in production

Before this commit, in the config bar (Sales or Invoicing) when you configure a payment
acquirer,  it was deployed in test mode, and not in production mode. Note that, the config
bar wizard asks for the production credentials.

Now, when you configure a payment acquirer, from the config bar, the acquirer is deployed
directly in production mode.
