The '_render' function of field widgets can be called several times in the widget's life cycle (each time its value changes). The JournalDashboardGraph appends a new 'svg' to its the $el at each rendering, so it must empty its $el at the beginning of each rendering. Before this fix, several graphs were displayed in the same kanban card in the Sales dashboard when, e.g., the user changed the color of the card.
