[Fix] No auto-scroll - swipe ability and prevent starting after release

- `canScroll` and `Plugin.prototype.play` functions revised again to remove conditional check of `this.options.by !== "none"` in `canScroll()` because this was preventing the content to be swiped to see all the content.
-  `onRelease` function modified to wrap existing logic inside a conditional check of `options.by !== "none"` so that if there should be no auto-scroll of the content then when a user has released, it should do nothing.
