global: apply new SQLAlchemy rules

* change from model Model.query to db.session.query(Model)

* without an update in pytest-invenio and without this commit it
  produces following error: sqlalchemy.exc.InvalidRequestError: Can't
  operate on closed transaction inside context manager.

* with the updated db fixture in pytest-inveniothis this commit fixes
  following TypeError: 'Session' object is not callable
