Empty or no Merchant ID provided when config is disabled for a website

[cyildirim]

Hi,

I get Empty or no Merchant ID provided error when config is disabled. But it works fine for the website openpay is disabled. This impacts when you have multiple websites on a magento instance.

Versions installed

openpay/sdk 2.2.1
openpay/magento2-banks 4.1.2
openpay/magento-cards 3.4.12

Steps to reporduce :

1. Have two different website on Magento instance 2 A and B
2. Enable & configure openpay cards for website A
3. Disable and leave empty openpay for website B
4. Go to website A cart page and observe everting works fine
5. Go to website B cat page and check exception Empty or no Merchant ID provided is thrown

**Expected **
Merchant id shouldn't be asked if openpay is disabled
