nCompton counter not working correctly for low SetCutInRegion values #711

Describe the bug

When the following setting is used:
/gate/physics/Gamma/SetCutInRegion world 0.1mm
The nCrystalCompton counter doesn't work correctly, neither in Hits or in Singles (rootfiles)

Example:
******************* Hits *********************************************************************************

• Row * eventID * edep * parentID * trackID * primaryID * PDGEncodi * nCrystalC * processNa *

•    3 *       296 * 0.4689259 *         0 *         1 *         1 *        22 *         0 *     compt *
  

•    4 *       296 * 0.1627675 *         0 *         1 *         1 *        22 *         0 *      phot *
  

•    5 *       296 *                0 *          1 *         2 *         1 *        22 *         0 *      Rayl *
  

•    6 *       296 * 0.0283064 *         1 *         2 *         1 *        22 *         0 *      phot *
  

When the cut is set to higher values, e.g. 1m, the problem doesn't occur and counting seems correct

Expected behavior
nCrystalCompton should increase when a compton interaction occurs in the crystal
