Flagsmith local evaluation can reuse stale traits from an earlier call

In local evaluation, pass the full trait set on every evaluation instead of relying on earlier calls. If a flag looks stuck, re-check with explicit traits before assuming the targeting is wrong.

Context: In Flagsmith local evaluation mode, supplied traits are not persisted to the Flagsmith API. On top of that, in @flagsmith/nodejs 9.0.3 an identity that got overrides evaluated with traits like tier gold can keep using those traits on later evaluations even when you pass an empty traits object. Your flag checks look sticky in a way you never configured.
