[ADAG] CompiledDAGFuture does not go out of scope cleanly

[ruisearch42]

What happened + What you expected to happen

When CompiledDAGFuture goes out of scope, we see the following exception:

Exception ignored in: <function CompiledDAGRef.__del__ at 0x7f06efd317e0>
Traceback (most recent call last):
  File "/home/ray/anaconda3/lib/python3.10/site-packages/ray/experimental/compiled_dag_ref.py", line 77, in __del__
    if not self._ray_get_called:
AttributeError: 'CompiledDAGFuture' object has no attribute '_ray_get_called'

This needs to be cleaned up.
