Fix repeated dbResets so tests run faster

* Set config.baseUrl and visit relative URLs to avoid Cypress bug which
  runs "before" hooks twice (github.com/cypress-io/cypress/issues/2777)
* Remove "after" hook dbResets; make tests responsible for their own
  initial state, not that of the subsequent test
