#### Previous behaviour
Steps to reproduce:

1. It syncs `thalia.nu` in mailinglists instead of the members domain because the env variable is wrong
2. The profile option for G Suite is missing

#### New behaviour
Steps to validate that it works:

1. It syncs using the right domain
2. The profile option is available
