4-status-not-updating-to-recieved-unless-all-items-in-order-are-recieved

Change to acq patron request status logic, which now looks like this:

If a cancel_reason is set on the patron request, then status = "Canceled"

If there is an associated hold request that has fulfillment_time set,
then status = 'Fulfilled"

If there is an associated lineitem has a state of "received", then status =
"Received"

If there is an associated purchase order with a state of "on-order" and an
associated hold request, then status = "Ordered, Hold Placed"

If there is an associated purchase order with a state of "on-order" but no
associated hold request (created through the automated process), then status =
"Ordered, Hold Not Placed"

If there is an associated lineitem (selection list), then status = "Pending"

If there is no associated lineitem, then status = "New"

Any other condition, which should be impossible (I should never say that), will
give a status of "Error"
