Fix the broken statistic generation

The output of msgfmt has different format if no fuzzy translations (or
even no translated) are available. I fixed that by parsing the output of
msgfmt more intelligent.

Drawback of the solution is that the parsing will not work if the output
of msgfmt use not the strings "translated messages", "fuzzy
translations" and "untranslated messages".
