[applets/batterymonitor] Fit it, pt.8: Fix null access error
Apparently, plasmoid
context property can turn into /dev/null before
its action does. Fixes the following error:
plasmoids/org.kde.plasma.battery/contents/ui/main.qml:166:
TypeError: Cannot read property 'configuration' of null
Let's keep up the pace! Next patch needs some splitting though, so it's gonna take another day or two.
