Bug#920340: 1.9 shows the same problem

[sergio]

The <host> from #919972 shows the same problem after upgrading to 1.9

Subject:
[package on hold] unattended-upgrades result for <host>: SUCCESS

Unattended upgrade result: All upgrades installed

Packages with upgradable origin but kept back:
 libcurl4


As I said in #919972 1.9 shows correct message "Packages with upgradable 
origin but kept back", but subject is wrong: "[package on hold]"
