sp_a5_credits no longer boots to the menu at the end of the credits

[vrad-exe]

When playing the credits from the New Game menu (not after completing finale4 normally), it now traps the player in a black box when the credits finish instead of booting to the menu as it did previously. The console indicates that Portal 2 now seemingly enforces the FCVAR_CLIENTCMD_CAN_EXECUTE convar flag since a recent update, but the credits weren't changed to call ClientCmd_Unrestricted when disconnecting the player so it now fails.
