Ben Wagner 6669b01267 Always check AutoFTAccess::face() for nullptr.
For various reasons AutoFTAccess::face() can return nullptr,
particularly in the case of fonts backed more or less by nothing, or by
users who keep plowing on using an SkTypeface which claims not to
actually have any glyphs. Clean up all the callers to do something which
makes sense when nullptr is returned.
