Problem with the "list" view

[ilbassa]

I have a problem with the "list" view:
The query
SELECT "language", COUNT(*) AS "cnt" FROM "language_translate" WHERE translation IS NOT NULL GROUP BY "language"
give me an error because the column translation is not quoted.

The problem is in models/Language.php, the line
->andWhere('translation IS NOT NULL')
should be
->andWhere(['not', ['translation'=>null]])

Could you fix this?
