In TCanvas::Build when a canvas is drawn from a TFile, fPainter is not defined and we get a crash. This problem was reported here: https://root-forum.cern.ch/t/segfault-when-drawing-canvas-stored-in-file/
This PR add a simple protection to avoid the crash. It fixes the problem. The canvas is Drawn as before.
May be @linev has a better fix has he did several changes in that area recently: https://github.com/root-project/root/commits/master/graf2d/gpad/src/TCanvas.cxx
