Add noscroll option to goto

Started this PR to implement #584

I think the feature is ready to merge.

I added a test, but I don't understand the error:

  1) scroll
       preserves scroll when noscroll is passed to goto:
     Error: No node found for selector: button
      at assert (node_modules\puppeteer\lib\helper.js:229:11)
      at DOMWorld.click (node_modules\puppeteer\lib\DOMWorld.js:359:5)
      at processTicksAndRejections (internal/process/task_queues.js:86:5)
    -- ASYNC --
      at Frame.<anonymous> (node_modules\puppeteer\lib\helper.js:108:27)
      at Page.click (node_modules\puppeteer\lib\Page.js:1021:29)
      at Context.it (test\apps\scroll\test.ts:101:14)
      at processTicksAndRejections (internal/process/task_queues.js:86:5)

I think I need some help to fix it.
