[steem.Post] get_all_replies() no longer works

[Netherdrake]

In [3]: len(list(p.get_replies()))
Out[3]: 43

In [4]: len(list(p.get_all_replies()))
Out[4]: 0

With the recommended usage:

Usage: all_comments = Post.get_all_replies(Post('@foo/bar'))

It does not work either.

Need to add tests to cover this case, and verify whether it is still happening.
