Fix race with hot-reloader-client clearing overlay errors (vercel#71771)

This `resolvePendingHotUpdate` in the `SERVER_COMPONENT_CHANGES` event
seems to be causing a race where an error would come through in a fast
refresh response and then the overlay would be cleared.

I'm not really sure why we were resolving a pending hot update here
because we already call it on `handleSuccessfulHotUpdateWebpack` and
`tryApplyUpdate` but I'm consistently seeing correct behavior without
this.
