## Summary Fixes a one liner bug where we were not using waitFor and could have stale views of data from the timeline. This removes that by adding a `waitFor` when setting the signals to be closed, open, in-progress, etc... This also adds a new `waitFor` for the end to end tests and fixes other tests to use that rather than doing a wait for 5 seconds. This should keep the end to end backend tests fast. Before this you could sometimes try to re-open 3 signals like below and it would not change the signals to being open but rather re-query the stale view and show the same signals as being closed when they are not closed:  Now with this PR, those signals will show as being re-opened and the closed signals will update correctly within the same UI on the same tab. ### Checklist - [x] [Unit or functional tests](https://github.com/elastic/kibana/blob/master/CONTRIBUTING.md#cross-browser-compatibility) were updated or added to match the most common scenarios |
