TSPLIBInstanceProvider only sets best known quality if also optimal tour is known

The TSPLIBInstanceProvider only sets the best known quality, if also an optimal tour is available for an instance. However, TSPLIB contains optimal tours only for very few instances, whereas the optimal quality is known for every instance. Therefore the TSPLIBInstanceProvider should be extended to set the best known quality correctly even if no optimal tour is provided in the TSPLIB.
