test(e2e): make browser close before tests run

[knagaitsev]

• This is a bugfix
• This is a feature
• This is a code refactor
• This is a test update
• This is a docs update
• This is a metadata update

For Bugs and Features; did you add new tests?

Motivation / Use-Case

Jest seems to have problems with the browser taking a while to close after a test has failed. Running tests after the browser has closed seems to be a workaround. I believe this will fix hanging on Windows CI.
