[Freeciv-Dev] (PR#9857) bugfix for single player gameload failure

["Mike Kaufman" <kaufman@xxxxxxxxxxxxxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=9857 >

In single-player mode if you attempt to load a game and it fails (you try
and load a non-savegame), then you can still click on the storesaved list
despite it being blank. It will start a game with no players and cause
trouble. This patch disallows that.
