Fix: connecting hair fails on meshes with no generative modifiers
Fixes a bug introduced in rB5dedb39d447b. `mesh_original` is not set if the
mesh has no generative modifiers, in which case we can use `mesh_final`, which
would seem to be consistent with the rest of the particle code. An alternative
approach would be to make sure that `mesh_original` is always set in
`deformVerts`.
