Bug 31259: Escape infinite loop when lime cannot wrap enough

Bug 31259: Escape infinite loop when lime cannot wrap enough

It seems the wrapping here works with words, not characters. If a line is too long,
or too far over, we can't trim it enough. We need to escape if successive loops are
not changing the line

To test:
 1 - Using sample data, edit the layout to match picture in comment 9
 2 - Add some borrowers to a batch
 3 - Attempt to export batch and save PDF
 4 - Staff client waits
 5 - ps aux | grep card
 6 - Note the job keeps running
 7 - Kill it
 8 - Apply patch
 9 - Restart_all
10 - Export batch again
11 - Success, you get a badly formatted PDF, rather than nothing
12 - Note the PDF does not show "Yakama Nation Library"
13 - Edit layout, male "Lower left X" 20 instead of 220
14 - Export again and note text field 1 shows correctly
