[FIX] website_quote, website_sale: calls to 'get_pdf' function

* get_pdf function expects a list of ids since the removal of old api in
  this commit: rev 47c67b640b
  There were still some wrong calls.
* while get_action can receive ids and recordsets, get_html and get_pdf
  are internal methods and still work with list of ids
