New entry creator fails for uncountable nouns in Portuguese

Hi there! First of all, superb work with the entry creation form — it's super convenient and very well done!

I did find a small bug, though. When creating a Portuguese noun, if I pick the "uncountable" option, it generates {{pt-noun|f|pl=-}}, which results in an error from Module:pt-headword, saying that the pl parameter is not recognized. The correct syntax appears to be as an anonymous parameter, i.e. {{pt-noun|f|-}}.
