JobTemplate read() seems requires unnecessary field 'audit_comment'?

[ssiuhk]

Hi,
According to foreman API doc apidoc/v2/job_templates/show.html, showing a job template should not require attribute audit_comment.
However, when I try to use the class to read a job template, it errors out with

>>> jobtmpl.read()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/sam/.pyenv/versions/3.6.1/lib/python3.6/site-packages/nailgun/entities.py", line 1614, in read
    ignore=ignore, params=params)
  File "/home/sam/.pyenv/versions/3.6.1/lib/python3.6/site-packages/nailgun/entity_mixins.py", line 822, in read
    setattr(entity, field_name, attrs[field_name])
KeyError: 'audit_comment'

Steps to reproduce:
On a fresh installed foreman server

>>> from nailgun.entities import JobTemplate
>>> from nailgun.config import ServerConfig
>>> server_config = ServerConfig(auth=('admin', 'pass'), url='https://foreman',verify=False)
>>> jobtmpl = JobTemplate(server_config, organization=[1])
>>> jobtmpl.search()

I checked the source code seems when ignore is None it will add 'template_input' into ignore.
Could you please check if 'audit_comment' should be added as well?
Thanks!
