Rendering of the left sources panel got broken
somewhere between gtk 3.10 and gtk 3.14, as some
treeview rendering mechanisms might have changed:
now OnRender is not called anymore when the width
is 0; so let's call the base implementation of
OnGetPreferredWidth() here instead.

This fixes the main glitch about using Banshee
2.9.x in Ubuntu 15.04, for example, which already
bundles gtk 3.14.x.
