Duplicates in dictionary.py for MS TTS

[sq6emm]

When running 'python microsoft_translator_downloader.py' with default dictionary.py you get some duplicates info, like:

metrow_na_sekunde already exists temperatura_odczuwalna already exists

I've run

$ grep Phrase pl_microsoft/dictionary.py | sort | uniq -c | grep 2
      2     Phrase(u"metrów na sekundę"),
      2     Phrase(u"temperatura odczuwalna"),

so it looks like there are only two duplicates.
