Fix bug when app is crashing when textField is empty in Rename controller. The reason was that the shouldEndEditing delegate method was blocking the end of editing when pressing cancel and dismissing the view controller. Fix was to remove this function since its functionality was included in the editingChanged handler which would deactivate the Rename button if the field is empty such either Cancel is possible or completion the text field with a valid name.
