Use Rails transactional tests
As of Rails 5.1:

  - Rails has built-in support for running tests within database
    transactions, so Database Cleaner is no longer needed for this.
  - Rails automatically shares the database connection across threads,
    so transactional_capybara is no longer needed.

Changes:

  - Enable `use_transactional_tests`.
  - Remove transactional_capybara.
  - Remove the Database Cleaner test wrapper.

This resolves:

  - transactional_capybara mismanages the shared database connection,
    causing the connection to falsely report as idle after the first
    test. At 6 minutes (idle_timeout + reaping_frequency) into testing,
    the connection is closed, causing e.g. `PG::ConnectionBad` errors.
