Source: Facebook marketing: raise a user config error when failing due to expired invalid credentials

[girarda]

Current Behavior

• The FB marketing connector currently raises a system error if the check operation fails due to the session being invalidated
• A session can be invalidated if the access token hasn't been used for more than 60 days, or if the users change their passwords
• Sample Sentry issue showing the failure_type was system_error

Expected Behavior

• Failures due to invalid access token should result in a config error to avoid creating sentry issues.
