Can create/update node with name "" in any api version

[Zhenguo Niu]

In API version below 1.5, we don't support specify node name, but it can pass if you set name="".

That's because we do check like "if name" instead of "if name is not None" before verify whether name is acceptable in the API version of this request.

    Correct api version check conditional for node.name

    Currently the name acceptable check is under the condition of
    "if name", so if you specify name to an empty value like "",
    that will skip the API version check.
