Bugfix #4923

Particle distribution error when using Vertex Weights.
In the unlucky case the last face in a Mesh has no weight (zero), the code
that tries to distribute particles evenly accidentally could assign it
still a particle, because of the 'remainder' calculus.

Also only happens in cases where the remainder has a value.
So a workaround is also to increase/decrease amount of particles.
