Title:
  override of APT_LISTCHANGES_FRONTEND can/should be removed

Status in unattended-upgrades package in Ubuntu:
  Confirmed

Bug description:
  unattended-upgrades overrides the setting of APT_LISTCHANGES_FRONTEND.
  per the comments, this was done at a time when apt-listchanges would
  "always send a mail if there is a mail address set in the config
  regardless of the frontend used."  this is no longer the case and this
  (now unnecessary) local override of APT_LISTCHANGES_FRONTEND can cause
  confusion when apt-listchanges appears to ignore its configured
  settings.

  What I expected to happen:

  i expected apt-listchanges to conform to its configuration.  setting
  the "none" frontend in /etc/apt/listchanges.conf should ensure it
  "Does nothing" as per the manpage.

  What happened instead:

  unattended-upgrades does not respect the frontend setting, essentially
  now replicating the bad behavior this snippet was originally meant to
  workaround (i.e., mail is currently sent when email_address is set but
  frontend=none).  with the attached patch the frontend specified in
  listchanges.conf is no longer unnecessarily overridden.
