Function misbehaving in wsfexv1.py

[chazuttu]

The function GetParamPtosVenta() in wsfexv1.py, returns null.

The xml returns fine but the fields are not returning, causing an empty list to be returned.

Evidence

On executing the following command:-
$ python -m pyafipws.wsfexv1 --prueba --ptosventa

-the following is returned, and it can be seen that at the end an empty array is returned,
where xml fields are expected.

See the function.
