Fix kotlin cache lazy loading
When USE_SCRIPT_COMPILATION_CACHE is set to false the classLoader is closed after the class is instantiated. This is causing an issue when lazy loading is happening during the script execution. Lazy loading occurs when a suspendible function returning something is called from "processNB", kotlin will create a second class that will be loaded during execution (needs to be in the classpath during execution).
