fix(napi): clear currently registering module slot (#19249)

This commit fixes problem with loading N-API modules that use 
the "old" way of registration (using "napi_module_register" API).
The slot was not cleared after loading modules, causing subsequent
calls that use the new way of registration (using 
"napi_register_module_v1" API) to try and load the previous module.
