Fix client use-after-free reported by mmmds

Fix https://github.com/teeworlds/teeworlds/issues/2645

The `Sv_ReadyToEnter` net message is only valid while we're still
loading stuff, it is used to signal that we can send the `ENTERGAME`
system message. Simply ignoring the server message while we're in the
wrong part of the state machine works.
