po: avoid crash when page is empty

Note that there is an associated po4a warning when a page is empty:
  Use of uninitialized value $file in substitution (s///) at /usr/share/perl5/Locale/Po4a/Text.pm line 205.
I've filed a bug with po4a about that, but the important thing is fixing
the crash here.
