[pyup-bot]

This PR updates django-allauth from 0.38.0 to 0.39.1.

Changelog

0.39.1

*******************

Note worthy changes
-------------------

- The ``linkedin_oauth2`` provider now gracefully deals with old V1
data that might still be present in ``SocialAccount.extra_data``.

0.39.0

*******************

Note worthy changes
-------------------

- New providers: JupyterHub (OAuth2), Steam (OpenID)

- Refactor translations: Portuguese (Portugal).

- Add testing for Django 2.2 (no code changes required)

Backwards incompatible changes
------------------------------

- ``linkedin_oauth2``: As the LinkedIn V1 API is deprecated, the user info
endpoint has been moved over to use the API V2. The format of the user
``extra_data`` is different and the profile picture is absent by default.
