Description of problem:
Right after creation _and validation_ of the container provider, when clicking on the edit (using Selenium), the page requires validation again. This is probably because the page ajax-loads the url https://$CFME/ems_container/ems_container_form_fields/$NUM where transiently the default_auth_status is False sometimes.

This breaks automation as it is then impossible to update the container provider (the validation is required).


Version-Release number of selected component (if applicable):
cfme 5.6.2.0.20160913114355_70e9086


How reproducible:
rarely 1/15

Steps to Reproduce:
1. Set-up https://github.com/ManageIQ/integration_tests
2.
import cfme.fixtures.pytest_selenium as sel
from utils import providers, version, conf
from cfme.configure import configuration 
conf.env['base_url'] = CFME_URL

from uuid import uuid4
from utils.update import update
p=providers.get_crud("cm-env2")
for i in range(15):
    if p.exists:
        p.delete(cancel=False)
        p.wait_for_delete()
    p.create()
    #sleep(10)
    with update(p):
        p.name="{}".format(uuid4())


Actual results:
Right after the container provider creation the Web UI thinks we are not authenticated to the container provider, but after a while all it changes it's mind and has no problems with the authentication

Expected results:
Once the provider is created and validated with correct token, the default_auth_status should be True
