po plugin: redesign refresh mechanism after master page update

manually triggering IkiWiki::refresh() was at least dubious, and more or less
buggy (it randomly broke the whole backlinks feature); thinking a bit more to
add the necessary bits to @needsbuild seems like a better way. don't play with
ikiwiki's internals if not absolutely needed.

 Misc. improvements
 ------------------
 
-### automatic POT/PO update
-
-- Use the `change` hook instead of `needsbuild`?
-- Fix (apparently harmless) undefined values that pollute logs when
-  saving a master page in the CGI
-
 ### page titles
 
 Use nice page titles from meta plugin in links, as inline already
