Smoketest remote: Multiroot test fails with no search results

[aeschli]

Ubuntu 18.04 LTS

• `yarn smoketest --remote --build /home/aeschli/vscode/1.38.0-insider-3db7e09f3b/VSCode-linux-x64/

Multi root test fails, no search result found

Same when running against source or on Windows.

Typing a space in the quick input box shows the result, so it looks like a timing issue.

Is there a way for the test to wait until the window is connected before triggering the search?

@aeschli I am now looking at the text of the status bar item to tell whether the window is actually connected. Let me know if that's not ok.

We could also add a class/id to that element.
