Comment ID changing on comment.refresh()

Issue Description

I do believe this is a bug:

        print(ancestor.id)
        ancestor.refresh()
        print(ancestor.id)

does not always print the same ID.

For example, I have a log entry which has:

item id BEFORE already_responded: dm6wi3q  # (code which is outside the scope)
dm6wi3q
dm6vozp
item id AFTER already_responded:  dm6vozp  # (code which is outside the scope)

I have not yet figured out the exact reproducible steps.

I’d recommend ignoring the comment if the second refresh fails.

@bboe Awesome. Nice find that doing a second refresh is the solution.
