Multiplayer Template: Client Disconnects Due to Component-Id Mismatch

[AMZN-Gene]

It's possible that MP template doesn't work. The server is unable to handle to first RPC packet received from the client and so it disconnects

Steps to reproduce

1. Start a new project using the multiplayer template
2. Setup a level with a Simple Network Player Spawner
3. CTRL+G to start the multiplayer simulation

Expected behavior
Server and client connects smoothly. Player loads.

Actual behavior
Server cannot handle an RPC (not sure which one), and disconnects from client
