Take explicitly set out_voa value into account in power calculation

Browse Source 
As mentioned in GitHub issue #409, an out_voa value for an EDFA
explicitly set in the topology file is not taken into account by
auto-design when calculating target power and gain. I think it is
more logical if the target power resulting from the optimization
algorithm represents the desired power into the fiber. This is also
more consistent with the behaviour for an automatically set out_voa
value when out_voa_auto is set to true.
