- undid part of the last commit and hopefully corrected it for good now.

We have to be extremely careful with the player data, because there's just too much code littered around that has certain expectations about what needs to be present and what not.
Obviously, when travelling in a hub, the player_t should be retained from the previous level. But we still have to set player_t::mo to the PlayerPawn from the savegame so that G_UnsnapshotLevel doesn't prematurely delete it and all associated voodoo dolls, because it checks player_t::mo to decide whether a player is valid or not.
The actual deletion of this redundant PlayerPawn should only be done in G_FinishTravel, after the actual player has been fully set up
