[FIX] point_of_sale: touch events are passive and allow resize with touch events

1. Methods associated to touchmove and touchstart listeners should not
call preventDefault because they are passive by default. Calling preventDefault
will do nothing but in chrome browser, error message is issued.
2. We now allow resize based on touch events.
