fix(jerryscript): fix memory leak in JS function handle deleter

The custom deleter for wrapped JS functions was not deleting the
jerry_value_t handle memory in some edge cases (context cleaned up,
wrong thread, etc.). Fixed by ensuring delete h is always called,
only skipping jerry_value_free when appropriate.
