Subject: [PATCH] Follow-up patch : catch CloneSubfield errors

A javascript error could occur if the CloneSubfield function failed for
any reason. This would prevent the popup from disappearing.

Example : Importing informations of a UNIF_TITLE authority with multiple
$x subfields in the biblio's 440 field. 440$x isn't repeatable, so an
error occurs when trying to clone it.
