Summary:Hi there,
This PR reorganises the flow for updating native props so that if you have a switch that's replaced with a spinner to handle a network action, you don't get a crash trying to update native props when an item may be moved out from underneath you. This was previously accepted but I had to rebase it so I just recreated it given it was a two line fix
Closes https://github.com/facebook/react-native/pull/6989
