Fix CFD-DEM restart (#1028)

Description of the problem CFD-DEM restarts were not working properly, leading a wrong value of the residual when restarting. This is due to the fact that the void fraction was being re-initialized when restarting when it should not. Description of the solution Remove void fraction reinit. How Has This Been Tested? One existing test has been modified to account for this change.

+### Fixed
+
+- MAJOR Restarts using lethe-fluid-particles with "void fraction time derivative = true" would be incoherent because the void fraction was reinitialized when restarting, leading to a wrong time derivative of the void fraction. This has been patched.
