Removed commented post.save call in puglishmenu

- The piece of code was commented out with an intention of keeping an existing pattern of only calling post's save's when edits are done in the editor or PSM. The changes in the publishmenu should not effect the model and have a need to save it
- The side-effect that still needs to be sorted is the change to the 'saveType' is effecting a model and causes a confirmation modal when leaving the post screen
