Bumped Flask-OpenID to allow people to upgrade to bridge release

Flask-OpenID version 1.2.5 cannot be installed with the recent
setuptools due to 2_to_3 useage. This has been solved by releasing
1.3.0 and updating constraints for all Airlfow 2 releases, but
we also should bump it for 1.10.15 to make it seamless for people
to upgrade to the "bridge" release in case they use an older
version of Airflow.
