Fix a bug in DynamicAutoDiffCostFunction

DynamicAutoDiffCostFunction::Evaluate when provided with a jacobians
array that was non-empty but all its entries are nullptr, would
compute num_active_parameters = 0, and then skip over all the loops
that evaluated the CostFunctor.

The fix is to check if num_active_parameters == 0, and then treat
it as the case where jacobians array is null.

Thanks to Ky Waegel for reporting and providing a reproduction for this.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.

Please see ceres-solver.org for more information.
