fix(debug): remove incorrect assert for nullptr in Overlap and EKinetic constructors (#7460)

Remove assert(this->SR != nullptr) in Overlap constructor and
assert(this->hsk != nullptr) in EKinetic constructor. These pointers
can be nullptr in normal operation (e.g., for force calculation),
so the assert was incorrectly triggering when DEBUG_INFO=ON.

Fixes #7021
