>> The call to `ClassLoader::load_class()` currently takes a Symbol* for the name and later extracts the string only to change it back into a Symbol* inside `ClassLoader::search_module_entries()` while also recalculating the package entry. This patch simply passes the string directly along with the package entry from the caller. Verified with tier1-5 tests.
