update migration tests

[circlecube]

These tests are failing in the latest bluehost release branch. Testing these seem fine, and referring to the cypress cloud videos, the tests step through and into the help-center properly, but the close button is not found when a click is attempted. I think the help is just taking a minute to load in the test but the test doesn't account for that.

• use more specific targets for the close button
• add timeout to the get method, hopefully it will be enough time to render the button
