Removing more than one line from the graph fails

[idoivri]

Although I try to remove lines from the graph, only the first one is being removed, and afterwards, while in the legend they are absent, they still appear on the graph.

Todo: remove 2+ lines from the graph, not only delete them from the legend... ;-)

First observation: Function draw in TimeLineCharts isn't being called.

Root cause: when 'legends_list.delete' event occurs (chart.js) it calls to render function of UiJet but this function supports only rendering once. Render in Base.js calls a constant first parameter=true, and the next rendering (e.g. removing second/third etc legend) won't be performed
