Fix SearchStack and ply misalignment in RootMoveList

Browse Source 
In RootMoveList c'tor we call qsearch() with
ply == 1 but SearchStack at 0.

We never noticed before because in qsearch we don't access
previous's ply SearchStack, otherwise we would have got
a nice crash ;-)

This bug is a fall down of previous patch.

No functional change.
