Fix vertex count estimate in GrTessellator.

Fix vertex count estimate in GrTessellator.

When we start a new MonotonePoly due to a handedness change, we don't need to
increase the vertex count, since that edge (and vertex) has already been
accounted for in the previous MonotonePoly.

This was not a correctness issue, but was causing us to allocate
extra vertices which would go unused.
