infoblox-client: Auth regression between 0.4.22 and 0.4.23

After this commit: https://github.com/infobloxopen/infoblox-client/commit/d85e570f6540efcd20c404897101a56c4257876a

I am able to login, but unable to perform write operations.

Example test script:

#!/usr/bin/env python3
  
from infoblox_client import connector
from infoblox_client import objects

params = {
    'host': 'some-hostname',
    'username': 'some-username',
    'password': 'some-password',
}

record = 'some.domain.example.com'

conn = connector.Connector(params)
existing = objects.ARecord.search(conn, name=record)
if existing:
    existing.delete()
objects.ARecord.create(conn, name=record, ip='1.2.3.4', ttl=60)

Traceback:
