LP1825851 Print template admin misc. repairs/improvements

1. When cloning a template, be sure the cloned template is available in
   the template selector regardless of whether it would have been given
   the current filters.

2. When cloning, set the 'active' flag explicitly to false so the user
   is forced to manually activate.  This prevent unintentional
   activation on in-process templtes.

3. When cloning, clear the owner value so the user is forced to select
   an owner value.

4. Allow the template editor textaread to expand vertically as the
   template gets longer (i.e. adds more new lines).
