The update fixes issues which surfaced when u-u switched installing updates in minimal steps, most notably the minimal-steps method being very slow

0.97 speeds up u-u ~90% which brings current worst-case (xenial with no security fixes -> fully updates) run-time down to tolerable levels.

Changes:
 unattended-upgrades (0.97) unstable; urgency=medium
 .
   * Handle recovering from broken dh_installinit override on Ubuntu, too
   * Declare needs-reboot for autopkgtests
   * Clean up more test artifacts
   * Run u-u-s only when running on AC power
   * Catch SystemError from fetcher.run(), too
   * Default to MinimalSteps=True in most tests to excercise default setting
   * Check only changed packages in check_changes_for_sanity()
   * Store candidate versions to adjust in UnattendedUpgradesCache()'s constructor
