[FIX] translations: don't skip first line of translations when extracting module names

Used to be the first line was the CSV headers, the slice was left over after
these were removed from the source data. It probably didn't hurt (only issue

term), but it's just as clean not to have that.

Also removed now-unused variable (probably leftover of the CSV thing as well)
