When creating the boundaries for the symmetry passess, it could happen that a symmetrical vertex is not found inside the radius of the brush. In that case, the function to initialize a new boundary was called with index -1 (BOUNDARY_VERTEX_NONE), so this function should also check that the initial vertex that is going to be used to find the boundary is a valid index.
