Remove translation console warning when accessing Administration - Applications Panel

2015-09-09 15:37:12,029 [http://localhost:8080/xwiki/bin/jsx/PanelsCode/ApplicationsPanelConfigurationSheet?language=en] WARN  .o.i.DefaultObservationManager - The [org.xwiki.localization.wiki.internal.OnDemandDocumentTranslationBundle] listener is overwritting a previously registered listener [org.xwiki.localization.wiki.internal.ComponentDocumentTranslationBundle] since they both are registered under the same id [localization.bundle.document:xwiki:PanelsCode.Translations]. In the future consider removing a Listener first if you really want to register it again.
