Title: Fix non-BMesh-containing .blend import

BlenderBMeshConverter was erroneously asserting that it contained valid
BMesh upon construction. The assertion should only occur when
triangulation is requested, allowing non-BMesh blender meshes to load
properly.

Note that this fixes a number of .blend regression tests that are
currently baselined as failures.
