Typo breaks nutritional information plugin schema upgrade

I'm the upstream maintainer. In the 0.16.1 release, I unfortunately mis-spelled the function name setup_nutritionconversions_table as setup_nutrition_conversions_table. This causes the following error (from [1]):

I've already patched the upstream code [2]. Please add this fix to saucy, as the bug would probably cause a lot of people complaining about the update breaking their recipe database!
