/usr/bin/update-manager:AttributeError:<lambda>:on_livepatch_status_ready

[errors.ubuntu.com bug bridge]

* Impact
The livepatch-reminder code added in 1:18.04.11.7 didn't take into account the case were users don't have software-properties installed and hits an error in those cases

* Test case
Uninstall software-properties-gtk and check that update-manager doesn't display errors when doing the testing from the SRU (lp: 1787553)

or check that the new version gets no errors report

* Regression potential
Check that the livepatch reminder shows as it should in an Ubuntu session

There are only 3 crashes with the version of the package in the Error Tracker bucket which I think are just apport noise, setting to verification-done.
