[Cbc] cbc.savedSolutionObjective() does not flip sign for max

[Matthew Galati]

Well - that was using cbc.branchAndBound().

The behavior is different for CbcMain().

The first solution is the right sign, the rest are not.

nSolutions=3
i=0 saved sol obj=279.9
i=1 saved sol obj=-279.43
i=2 saved sol obj=-279.28

Unless there is only one solution, then the sign is wrong for even for the
first solution:
nSolutions=1
i=0 saved sol obj=-282.4
