clickSelector only clicks first element found

In `clickAndHoverHelper.js` the line `await page.click(clickSelectorIndex);` only clicks the first element found. It should click all elements found with the given selector.

Suggested fix:
`for (var element of document.querySelectorAll(clickSelectorIndex)) {
					element.click();
				}`

This might also be the case for `page.hover()` and `page.type()` (keypress)
