Deja-dup asks to install software from un-trusted sources

[Jamie Coombs]

When setting up deja-dup to backup to Google drive, it says that dulicity & python-gi are not installed (this is expected). It gives the option to install these packages, but the system warns that they are from an untrusted source.

Installing the same packages from terminal raises no such warnings.

Should be fixed in 19.10 by hard depending on the packages.
