CALL Node for len has no CALL_CALLEE child

[zurk]

If you get UAST for len(x) you will get no CALL_CALLEE child in CALL Node but the documentation (http://godoc.org/github.com/bblfsh/sdk/uast#Role) says:

// Call is any call, whether it is a function, procedure, method or macro.
// In its simplest form, a call will have a single child with a function
// name (CallCallee).

So, as I understand any CALL should have CALL_CALLEE child.

It seems that any function does not have CALL_CALLEE child.
I run:

res = BblfshClient("0.0.0.0:9432").parse('example.py', language='Python')
print(res)

and example.py is

def function():
    pass

function()

here you can find full UAST: https://gist.github.com/zurk/4764b6a9d04c8ba6bbe8b6385c1d5f60

Also I found that it has two CALL nodes. Line 138 and 152.

Thanks @zurk. I can confirm both bugs. In the future please report a single problem per issue for better tracking.
