Booking title change confuses item-based resources

[Mike Rylander]

When the title of the bib for a barcoded, bookable resource changes (that is, when the resource type gets a new name), we create a new bookable resource type. We do this in order to maintain historical information about the title (resource type) for reporting purposes. However, we only allow a barcode to exist once as a bookable resource, and we depend on the type's name to find the list of possible resources during the booking process. Because of this, the resources become, effectively, unbookable.

If we allow that the resource type's name may change automatically when the backing bib record is edited, then the fix is straight-forward: find the resource type by record and owner (ignoring name) and update the name on the type.

However, if maintaining the historical information associated with the title (say, the whole bib is replaced with a different and unrelated one), then this is dangerous for reporting and statistics.

[NTS: OpenILS::Application::Booking::get_existing_brt is what needs modification to maintain title changes.]

I suspect this is a duplicate of https://bugs.launchpad.net/evergreen/+bug/1022764. Can somebody more familiar with the booking module confirm? Thanks!
