Title:
  Replacing configuration file directory with file breaks unattended-
  upgrades

Status in unattended-upgrades package in Ubuntu:
  Fix Released
Status in unattended-upgrades source package in Xenial:
  Fix Committed

Bug description:
  [Impact]

   * Unattended-upgrades crashes when a package update changes a config dir to a config file.
   * U-u stops installing security updates when it crashes.

  [Test Case] (Xenial)

   * Install an older version of the git package than the one available from xenial-security:
   # apt install git=1:2.7.4-0ubuntu1

   * Change a configuration file to a directory and observe not fixed u-u crashing and fixed u-u installing the update.
  # mv /etc/bash_completion.d/git-prompt /etc/bash_completion.d/git-prompt.bak
  # mkdir /etc/bash_completion.d/git-prompt
  # unattended-upgrade --verbose --dry-run
  Initial blacklisted packages: 
  Initial whitelisted packages: 
  Starting unattended upgrades script
  Allowed origins are: ['o=Ubuntu,a=xenial', 'o=Ubuntu,a=xenial-security', 'o=UbuntuESM,a=xenial']

  dpkg: warning: git: conffile '/etc/bash_completion.d/git-prompt' is not a plain file or symlink (= '/etc/bash_completion.d/git-prompt')
  ...

  [Regression Potential]

   * As a known and demonstrated regression configuration files replaced
  with directories by the local administrator are overwritten and this
  is dpkg's default behavior. The same thing would happen when applying
  the security update using apt, and this is still better than skipping
  the security update.
