We have conflicts which prevents us from running demo seed command after
a database-reset or/and if dev seed has already been populated. This is
because we are trying to create Tim user twice (but due to the
insert()...onConflict() in the seed creation, it does not create the
second one), for seed-dev and seed-demo .
This PR fixes that by using the same user id, allowing us to use the
same Tim apple for both dev/demo seeds
