Fix assert triggered when snapping to evaluated geometry of a Curve

Curves can have a Mesh evaluated, but only objects of type Mesh have
EditMesh.

This bug is harmless because `sctx->editmesh_caches.remove(value)` only
works with pointers and `BKE_editmesh_from_object(ob_eval)`, even though
it doesn't actually return a `BMEditMesh`, it still returns a pointer
that doesn't exist as a key.
