#1 Bad Import of blanked out Translations

[Stephane JAIS]

To reproduce, you must have 2 installations of Cantina
with two independant datasources, and distinct search
indices.

On installation A, create a document "myDocument" and a
translation in a Locale with the words "cannot find".
Create a Backup of installation A from its web GUI.

Import that backup to installation B and check in its
web GUI that the document has been well imported.

On installation A, blank out the translation.
Export installation A again, and import it in
installation B.

On installation B, access the document "myDocument" via
the web GUI: the translation has not been blanked out.
