Fix ssh-completions when there's no includes (#1065)

Browse source 
The ssh-completion didn't work when I first tried to source it. Turned
out that `reduce` failed when `$includes` was an empty list:

```nushell
$includes | par-each {|p| $p | open --raw | process } | reduce {|it| merge deep $it --strategy=append }
```

The change proposed in this PR fixes the problem so the completion also
works if there are no includes in the ssh config files. I'm a total
nushell beginner though, so I'm not sure if it's the best or the most
idiomatic way to solve the problem :)
