Update keyring to 13.0.0

[pyup-bot]

This PR updates keyring from 12.0.1 to 13.0.0.

Changelog

13.0.0

------

* 327: In kwallet backend, if the collection or item is
locked, a ``KeyringLocked`` exception is raised. Clients
expecting a None response from ``get_password`` under
this condition will need to catch this exception.
Additionally, an ``InitError`` is now raised if the
connection cannot be established to the DBus.

* 298: In kwallet backend, when checking an existing
handle, verify that it is still valid or create a new
connection.

12.2.1

------

* Fixed issue in SecretService. Ref 226.

12.2.0

------

* 322: Fix AttributeError when ``escape.__builtins__``
is a dict.

* Deprecated ``keyring.util.escape`` module. If you use
this module or encounter the warning (on the latest
release of your packages), please `file a ticket
<https://github.com/jaraco/keyring/issues/new>`_.

12.1.0

------

* Unpin SecretStorage on Python 3.5+. Requires that
Setuptools 17.1 be used. Note that the special
handling will be unnecessary once Pip 9 can be
assumed (as it will exclude SecretStorage 3 in
non-viable environments).

12.0.2

------

* Pin SecretStorage to 2.x.
