BMesh: Fix BM_face_loop_separate_multi

When the loop region passed in had no loops to edge-split from,
it was assumed nothing needed to be done.

This ignored the case where loops share a vertex
without any shared edges.

Now BM_face_loop_separate_multi behaves like BM_face_loop_separate.

Fixed error where faces remained connected by verts in BM_mesh_separate_faces.
