po: Fix copy of po file from underlay when editing

When first editing a page that was in the underlay, avoid losing
the translation by copying the po file over from the underlay.

-Bug when editing underlay file
-------------------------------
-
-While I've gotten translated underlays working, there is a bug
-if the wiki is currently using a page from the underlay, and the master
-language version is edited. This causes the edited page to be saved
-to srcdir.. and all the translations get set to 0% and their
-po files have the translated strings "emptied". What's really going on
-is that these are entirely new po files not based on the old ones
-in the basewiki, and thus lacking translations. --[[Joey]]
