Bug description:
[Impact]
* Unattended-upgrades fails to install updates when adjusting
candidates is needed.
[Test Case]
Note that only 1.2ubuntu1 is affected. Earlier releases either did not
crash or did not adjust candidates due to LP: #1775292. To reproduce
the crash Cosmic's u-u 1.2ubuntu1 needs to be installed.
* Run sudo apt update && sudo unattended-upgrade --dry-run --verbose --debug
* Observe no line with "adjusting candidate version: " or a crash with buggy
u-u versions

[Regression Potential]
* Unattended-upgrade may crash when adjusting candidates preventing
upgrades to be installed
