SQLAlchemy sessions and live_server

[citizen-stig]

I use pytest-flask with pytest-flask-sqlalchemy. It works fine, except for live_server. More details are available in pytest-flask-sqlalchemy issue 17 and repo with example

I'm sorry if this problem is not related to pytest-flask, but maybe I can find help here with investigation. I believe it might be common use case, to have selenium tests and sqlachemy session together
