Revert "Merge branch 'backport_latest_byzantium_0.3.0-2' into 'pureos/amber-phone'"

This reverts merge request !5 because there are some issues with
crashing calls in certain conditions (related to gnome-online-accounts)

Therefore I think it would be best to just backport relevant
fixes instead of pushing the new version.
