Passing expire_on_commit=False on sessionmaker() [see #181]

Browse source 
Accessing db objects outside of their session seems to fail on SQLAlchemy >= 1.4
with a `Instance `Instance <x> is not bound to a Session` error.

Setting expire_on_commit=False on the session seems to somehow fix the issue
(see https://stackoverflow.com/questions/3039567/sqlalchemy-detachedinstanceerror-with-regular-attribute-not-a-relation)
