[SantiParagarino]

The ping to check if the API is available for the cron job to run is made before checking if all the ecommerce settings are correctly set up.

Preconditions

Steps to reproduce

1. Enable only one store view to send ecommerce data leaving another disabled.

Expected result

1. Everything runs okay without errors.

Actual result

1. The ping call fails adding an error in the logs when it should not.
