Fixed an assertion that was sometimes failing for TestAIModule's TestMap...

...1, about units moving at the start of the game. Using a debugger, I can see that BW's memory for the units at the start of the game shows that some units have a move order. FYI, in the old version this can usually be reproduced by starting a game for MicroTest.scm (with Use Map Settings) for a few seconds then quit mission then start a game for testmap1.scm (with Use Map Settings).
