Movement Not Working When Possessing a Player Pawn on Second Client

Possessing a pawn on a second client while using a dedicated server prevents the pawn from moving until net.shareshadowstate is set to false.

This appears to be a regression. I was not able to reproduce the behavior in 4.13.2

1. Open the attached project
2. Set PIE settings to 2 players and Run Dedicated Server
3. Press K on the first Client to possess a pawn. Notice the pawn can move
4. Press K on the second Client to possess a pawn.
5. Attempt to move around in the level

Result: This pawn is unable to move. Setting net.shareshadowstate to false allows the pawn to move.

Expected: The pawn would be able to move as the first client is.
