runhistory in choose next

[Aaron Klein]

The choose_next() method in the SMBO class accesses the runhistory, which is initialized in the run() method. However, in some cases (such as labwatch) we only use the choose_next() functionality of SMAC without ever calling the run method. Because of that, we should either avoid accessing the runhistory object in choose_next() or initializing it in the constructor.
