lua: function takes only one parameter by default instead of 2

Needs random tests.

The tests are currectly executing user code twice for every test case. This effectively doubles the runtime for most people ;-)

Sample tests:

In file included from main.cpp:7:
./tests.cpp:51:17: error: use of undeclared identifier 'isSafe'
            if(!isSafe(last_island, current_island, current_test.bridges)){
                ^
1 error generated.

Actual tests:

In file included from main.cpp:7:
./tests.cpp:31:48: error: use of undeclared identifier 'createGraph'
         std::vector<std::vector<int>> graph = createGraph(current_test.islands_amount, current_test.bridges);
                                               ^
1 error generated.
