test: retarget first-directory-only case onto LS_LoadSegformerModel

#14489 de-registered the QwenVL family from MODEL_NODE_MAPPINGS, which fixed
the reported symptom but left the underlying bug class untouched: the asset
browser still resolves a node type to exactly one category and queries only
that directory.

Retargets the it.fails case onto LS_LoadSegformerModel (3 registered
directories, the worst remaining case) so the test dies honestly when the
bug is actually fixed, rather than documenting an example that no longer
exists in the product.

Verified failing for the right reason: include_tags resolves to
'models,segformer_b2_clothes', so segformer_b3_clothes and
segformer_b3_fashion are unreachable.

Still live on main as of 2026-08-03 for 5 node/input pairs; see the comment
block for the full list.
