Allow comet tails on vanilla bodies (#1069)

Made this because I tried to add a comet tail to ember twin but it kept
saying `Comet CaveTwin_Body does not orbit anything. That makes no
sense` because Orbit.primaryBody didn't have anything.
So now it grabs the primary body from the astro object but also takes
into account Orbit.primaryBody

## Bug fixes

- Fixed a bug that didn't allow comet tails to be made on unmoved
vanilla planets/moons.
