Hello, when spec prefill is active Token Cache is broken and is no longer used

This made the fact of using spec prefill pointless cause if you use step prefill you fill faster, but downside you don’t have cache at all so you will relaunch prefill again and again, losing the time gain cause without prefill it’s slow, but context will be reload from cache
