IslandGA does not work with stochastic evaluator — at Version 1

Description (last modified by mkommend)
The reason is that every island has a local RNG which is initialized in the IslandGAMainLoop. However, the first call to the evaluator happens outside the main loop directly in the SolutionsCreator and hence throws an exception as the RNG is not initialized. Using the global RNG is not a solution as this would lead to race conditions if a parallel engine is used.
This might also be an issue for the IslandOSGA.
