I don't think that's how light works. Once a photon leaves its star they are separate and the photon will carry on regardless of the fate of what ever source it was created by. That's why, as Cthulhu Dreaming mentioned, it takes time until the last photon from a dying star reaches us and it disappears from our sky. So they aren't connected, the photon and the star, the light of a star is just a continuous stream of photons.
And when the star dies its last photons are sent out and it's sort of like unplugging your vacuum cleaner and rolling up the chord, it takes time before the end of the chord reaches the vacuum cleaner. Basically the earth is a vacuum cleaner and stars are just millions of chords that may or may not be rolling up right now and we won't know it until the final photon reaches us.
