Prefilling an oil filter is not necessary because everything has a thin coating of residual oil which lubricates internal parts until oil pressure builds. And when the engine is restarted with an empty oil filter, it should be left at idle speed until the oil pressure / teapot light goes out (should be around 5 seconds depending on the vehicle and filter). The engine has very little pressure and stress at idle speed so nothing is getting excess wear while the filter primes.
Many of us prefill our oil filters just because it makes us feel so much better when the oil light turns off immediately.
