LP#1551447 Selfcheck: Printing Fines Prints All Open Transactions

This corrects the behavior of the selfcheck fines receipt print template.
Prior to this, it printed all open billable transactions (eg, every item
that the patron had checked out) regardless of whether or not it had bills
associated with it. This adds a small bit of logic to the template to
check for a balance due. It also updates the javascript to check for a
balance on the account before launching the print function to prevent the
system from taking unnecessary action.

This includes a SQL upgrade script to update the Self-Checked Fines
Receipt template for systems that are already in production, as well as
including an update to the seed data.
