If passwords file exists, passing in passwords dictionary to interface.run does not work

[clickthisnick]

If there is already a serialized passwords file, then passing passwords into the interface.run fails.

To reproduce, run this twice. On first run it works fine (And serializes the /runner/env/passwords file)
On second run it fails, since that file exists.

import ansible_runner.interface

kwargs = {}
kwargs['playbook'] = 'test.yml'
kwargs['private_data_dir'] = '/runner'
kwargs['passwords'] = {"SSH [pP]assword:": "password"}

stdout = ansible_runner.interface.run(**kwargs)

Error:

Traceback (most recent call last):
  File "runner.py", line 11, in <module>
    stdout = ansible_runner.interface.run(**kwargs)
  File "/opt/ansible/3.6.5/lib64/python3.6/site-packages/ansible_runner/interface.py", line 210, in run
    r = init_runner(**kwargs)
  File "/opt/ansible/3.6.5/lib64/python3.6/site-packages/ansible_runner/interface.py", line 74, in init_runner
    rc = RunnerConfig(**kwargs)
TypeError: __init__() got an unexpected keyword argument 'passwords'

At this point if I rm -rf /runner/env/passwords then run again, it will work.

I'm not sure the expected outcome, but I would have thought passwords would have merged into or overridden the serialized passwords file.
