test(javascript): expect unknown provenance for a shadowing parameter

c7a890d12 deliberately keeps parameter provenance unknown ("Parameter
provenance depends on caller arguments.") instead of the previous
implicit local fallback, but the structure test still expected the
shadowing `ipcRenderer` parameter to be local, so it fails on main and
in every PR's domain shard. The test's purpose, that the parameter does
not inherit the module alias it shadows, is unchanged.
