QQuickItemParticle give() method kill particle

Currently removing an item connected to a particle
only invalidate the particle that will be reused for
the next item set. This has the effect that the new
item inserted appears in the same position as the
old one just removed. This patch force killing the
particle to assign next item to a new particle
starting from initial position.
