Fixed regression bug where file would be lost
Fixed regression bug where file would be lost

This commit changes how processRawFieldData works, by updating current languages values in the database (this was the role of the _fakeDefaultFile() method that got deleted).

The new implementation only uses an UPDATE statement to do so and makes sure to overwrite the 'default' columns to map the default language
