pica_add() doesn't work if hash key 'record' not exists

[jorol]

$ echo '{"title":"code4lib"}' | catmandu convert JSON to PICA --type Plain --fix 'pica_add(title,021A$a)'
PICA record must be array reference
$  echo '{"title":"code4lib"}' | catmandu convert JSON to PICA --type Plain --fix 'pica_add(title,021A$a,record:"pica")'
PICA record must be array reference
$echo '{"title":"code4lib"}' | catmandu convert JSON to YAML --fix 'pica_add(title,021A$a)'
---
title: code4lib
...

Works if key is defined beforehand:

echo '{"title":"code4lib"}' | catmandu convert JSON to PICA --type Plain --fix 'set_array(record);pica_add(title,021A$a)'
021A $acode4lib

I'll create pica_update(PATH, value) instead and depracte pica_add because of the order of arguments (see #82).

Fixed in 1.14 to be released today.
