[Evolution] Evolution 3.15, Fedora 22 and Gnome Online Accounts

[Zan Lynx <zlynx acm org>]

Evolution, or perhaps GOA has managed to screw backup and recovery yet
again. Do they ever think these things through?

A full account restore from a system of a different host name resulted
in doubled online accounts in $HOME/.config/evolution/sources.

Like so:

$ grep AccountId=account_1425514256_0 -r .
./1425514256 2013 0 orpheus source:AccountId=account_1425514256_0
./1426523640 2025 14 felis source:AccountId=account_1425514256_0

Now really what kind of sense does that make?

I haven't looked into it all the way. This might be GOA's fault. But
anyway. Suuuuper annoying.
