js-translation.json generation broken in 2.1.4

[thomvanderboon]

After update from 2.1.2 (via composer) to 2.1.4 only empty js-translation.json files are generated. It worked great under 2.1.2.

Preconditions

1. Install 2.1.4
2. Use f.e. the Magento Crowdin Translation package to translate your site

Steps to reproduce

1. From document root run the following commands

cd app/i18n/test/nl_nl
/bin/rm source_nl_NL.csv
wget http://107.170.242.99/var/2.1.0/source_nl_NL.csv
cd /../../../../
#back to document root
find . -name js-translation.json -exec rm -rf {} \;
php bin/magento setup:static-content:deploy en_US nl_NL
php bin/magento indexer:reindex
php bin/magento cache:clean
php bin/magento cache:flush

Expected result

1. Correctly generated js-translation.json

Actual result

1. Empty js-translation.json (contains only [] )

Little bit further testing and I found a work arround. If you run the deploy command with multiple languages, it is broken: f.e.

php bin/magento setup:static-content:deploy en_US nl_NL

The js-translation.json is generated correctly if invoked as separate commands for each language. f.e.

php bin/magento setup:static-content:deploy en_US
php bin/magento setup:static-content:deploy nl_NL

This problem started from 2.1.3

Jep this is a bug since 2.1.3 - before it worked without a problem.
