NetworkTransformUnreliable Rigidbody demo initial jitter if onlySyncOnChange is enabled

[miwarnec]

• open rigidbody demo
• in hierarchy, find Server Ball A, enable 'only sync on change' in RigidbodyUnreliable if not enabled yet
• build & run. build = server-only
• editor=client
• server: press space once
• notice on the client, the unreliable ball moves up a bit immediately, then waits for 2-3 frames, then moves smooth
• reliable one is just fine. onlySyncOnChange disabled is just fine

here is default, without onlySyncOnChange: notice it's smooth https://github.com/MirrorNetworking/Mirror/assets/16416509/27edcb00-34f2-4da4-b012-4bb9c4d2463c

here is with onlySyncOnChange enabled: https://github.com/MirrorNetworking/Mirror/assets/16416509/3548d860-e684-4b3f-8260-0344eeb30968
