Fix the case where the yield is zero.
...
Problem detected in the context of a code-to-code comparison between OpenMC and TRIPOLI-4:
- configuration: sphere of radius R = 30 cm containing the isotope ZR93 at 293K
- sphere irradiated at the center by an isotropic, mono-energy, point source (E_0 = 14.1 MeV)
- data from JEFF-3.3
For some isotopes, namely ZR93 at 293K, the sampled yield can be equal to 0 (namely for MT=5: interaction "n-other").
In such a case, it is necessary to deactivate the particle.

Use nu_bank_ for fixed source mode too
...
Right now, if an outgoing energy filter is used with a nu-fission score in fixed
source mode, OpenMC will segfault because it tries to pull information on
fission sites from nu_bank_, which is not currently populated.
