cubicweb #343519 i18n: _('add') automatically prepended to some msgstr [open]

for LinkToEntityAction like strings, one automatically prepends _('add') to the msgstr

this is wrong for several reasons :

  • it is completely unobvious for the .po file maintainer, eg this is wrong:

    msgid "add DeletedVersionContent content_for VersionedFile object"
    msgstr "ajouter ce fichier supprimé dans l'entrepôt"
    
  • it can happen (albeit not frequently, nonetheless meaningfully wrt the domain) that the standard transaltion for _('add') is not adequate, eg one case were we want something different:

    msgid "add DeletedVersionContent content_for VersionedFile object"
    msgstr "supprimer ce fichier de l'entrepôt"
    
  • I expect that for non-latin languages the verb might not be correctly placed in first position
