Bug 30583: Fix hold system for translated templates

Bug 30583: Fix hold system for translated templates

There are missing quotes, and the translate script is messing up with
the generated template.

Error is:
Template process failed: file error - parse error - holds_table.inc line 216-217: unexpected token (hold)

The generated line, without this patch is:
216 <td><input %]="%]" class="printholdslip" data-reserve_id="[%" hold.reserve_id="hold.reserve_id" html="html" name="printholdslip" type="button" value="Recibo" |="|"></td>
With this patch applied:
216  <td><input class="printholdslip" data-reserve_id="[% hold.reserve_id | html %]" name="printholdslip" type="button" value="Recibo"></td>
