Prevent Bedrock from changing gamemode client-side (#1337)

Browse source 
In vanilla Bedrock, if you have operator status, the client sends a packet to change gamemode without confirmation from the server. Since we have a custom server option to request the gamemode, we just reset the gamemode and ignore this packet.
