Wait for disable_stream_notifications selector to be visible
before clicking as it could cause flakes if the test tries
to click without it being visible.
Added a stronger validation of waiting for text "Verona" to
appear but that didn't really seem to have worked though it
seemed like fixing the flake by passing ~600 runs.
So, change the puppeteer click to a click through evaluate
as we had experiences where page.click() didn't work sometimes.
Though this has passed 1000 runs on CI, I'm not very certain
if this fixed it as this test passed 1000 times with my previous
PR fixing the same flake.
This flake occurs because the Verona dropdown menu couldn't be
clicked, in rare cases, because puppeteer would click it too
quickly before it appears and then fails. To fix this we wait for it
to fully appear and then click it. Around 1000 runs
passed without a failure.
The error the flake caused was:
TimeoutError: waiting for selector
"#org-submit-notifications[data-status="unsaved"]" ...
