Fix T47983: Particles - Emit from Verts emits double on one vert.
When non-random, particle distribution used a small start offset (to avoid
zero-weight faces), which is fine with "continuous" entities like faces, but not
for discrete ones like vertices - in that case it was generating some undesired
"jump" over a few verts in case step was small enough
(i.e. total number of verts/particles was big enough).
