[chain_redesign] Change behavior of try_get_chain_position
`TxGraph::try_get_chain_position` used to always exclude unconfirmed
transactions with last_seen value of 0. However, what is the point of
including a transaction in the graph if it cannot be part of the chain
history? Additionally, maybe sometimes we don't wish to use the
last_seen field at all.

The new behavior will consider unconfirmed transactions with last_seen
of 0.
