Fix Valgrind warnings appearing during the test suit.

Please take a look if I did put the initialization parts into the right places (ctor/init ?). There remains one particular issue about AiPlayerBaka.cpp:1239 that reaches into the stl and hits set/map code. The stl accesses an uninitialized value for comparison here but I am not sure how to fix that.

```c++
                    if(a->getActionTc()->maxtargets == 1)
                    {
                        OrderedAIAction aiAction(this, a, c, t);
                        ranking[aiAction] = 1;  // <-- this line
                    }
```

Please note that this patch also fixes the failing test in https://github.com/WagicProject/wagic/pull/572
