Title: Fix for segmentation

Commenting for now `_validate_expression()` calls as it was preventing the lib to be used.
This PR also add a filter on the parameters and remove all the empty ones as Mixpanel does not seems to like it and return a 400 Bad request.
This PR also fix the segmentations parameters lists and the urls.
