modified the tooltip react entry to either show 👍 or Unlike depending on whether the user liked the message. Happy to make this look better, but I figured since this is a temporary solution that will be reverted once we go from message liking to message reactions, it wasn't worth spending a ton of time to make this perfect.
I also modified the destructiveButtonIndex to only have a value if the Report option is present. As I was making the changes above, I noticed that Unlike was turning red when a viewer was trying to unlike their own message.
Depends on D5813
