chore: remove needless borrows in pet-hatch tests (Fixes #481)

PathBuf already implements the traits required by norm_case, so the
extra & borrows tripped clippy's needless_borrows_for_generic_args lint
under newer clippy versions, breaking the documented
cargo clippy --all -- -D warnings pre-commit gate.
