Fix T68489: Shrinkwrap modifier with project not working for curves

rB4cde92303f3d made a MESH-only check (but that is no longer mandatory
since the Mesh is fetched by MOD_deform_mesh_eval_get instead of ctx-
>object->data now...). This would fail for projecting beveled curves
(resulting mesh missing), now also get the mesh for curves if we use
MOD_SHRINKWRAP_PROJECT (and only then).
