py-google-api-python-client: updated to 1.6.5

Version 1.6.5

Bugfix release
- Proactively refresh credentials when applying and treat a missing
  access_token as invalid. Note: This change reveals surprising behavior
  between default credentials and batches. If you allow
  googleapiclient.discovery.build to use default credentials *and* specify
  different credentials by providing batch.execut() with an explicit http
  argument, your individual requests will use the default credentials and
  *not* the credentials specified to the batch http. To avoid this, tell
  build explicitly not to use default credentials by specifying
  build(..., http=httplib2.Http().
- Remove mutual exclusivity check for developerKey and credentials
- Handle unknown media length.
- Handle variant error format gracefully.
- Avoid testing against Django >= 2.0.0 on Python 2.
