Fix error 222 in alta-open-lambda

[robz]

The alta-open-lambda fails 1-2% of the time, due to a 222 error. It seems we need to handle the response and update the merged account:
https://developer.neoncrm.com/accounts/#handling-http-222

Examples:

[ERROR] ValueError: Get https://api.neoncrm.com/v2/accounts/9244 returned status code 222
