ivi-shell: set an initial value for ivi-surface.

Especially, the size of destination rectagle is set to (1,1).
This is because the size will be used for caluculating scale and not to
be 0 to avoid 0 dividing.

I also remark this as FIXME. This shall be fixed at ivi-layout-tansition.c.
In new invoded application, its property is initilized by (0,0)
destination rectangle. So transition fucntion always calculates its scale
as inf at first frame of fade-in with new invoked application. To fix this,
restructing transition function is ideally needed.
