    Restore original time override in test_archive_task_logs

    Change I9b16a3a849937aba5b90ed1ab9a80b7f0103f673 attempted to fix a
    non-determinstic failure in the test_archive_task_logs functional test
    by adding a time override. That fix however missed that the
    osloutils_fixture.TimeFixture clears the time override when it exits
    and that does not mean a previous time override will be restored.

    This removes usage of the osloutils_fixture.TimeFixture and instead
    sets time overrides and restores previous time overrides. Restoration
    of the original time overrides also made an adjustment to the --before
    option value necessary in order to pick up the first task_log record.
