commit b8ce2b545ac83ff6e5d059a1c15c33b4789d024d

    [stress-test] run tests on empty book and populated book
    
    Refactor (tests) into call (create-test-data) which will add sample
    txns in the environment.
    
    As a result we can run tests twice - once before and once
    after (create-test-data) which helps dislodge a few more report bugs.
