The infamous "Cliquer pour déplier ou plier le détail de l’opération" is
back!

This is linked to the commit 6d41bfaf that removes this piece of some
transaction labels ; but it turns out that now it's not located in
parts[0] instead of parts[1].
I first remove all empty strings and then look for the string that we
want to get rid of ; if it's there I remove it from the list, this way
it is more dynamic that parts[0] or parts[1].

Tested with CIC and creditmutuel connections.
