Barcode image not rendering on staff slips - fails gracefully

Overview: The staff slips tokens item.barcodeImage or requester.barcodeImage do not render as an image on all staff slips, including hold, transit, request delivery and pick slip.

Steps to Reproduce:

1. Go to Settings > Circulation > Staff slips and ensure hold staff slip has one or both barcode image tokens ( item.barcodeImage and/or requester.barcodeImage )
2. Create a page request (item should be available) and note pick up service point
3. Make sure your service point (at top right) matches the one selected in the previous step
4. Check in item
5. Print hold slip

Expected Results: Tokens should render as a barcode image

Actual Results: Tokens render as

<Barcode>908897786564</Barcode>

Additional Information: It fails gracefully so not a top priority. I also tested all other staff slips and it does not render properly on any staff slips. This might be related to a similar issue that was recently fixed MODTEMPENG-57.
