Set-nbObject LookUps not working

In Set-nbObject.ps1

it is checking, if it needs to lookup for the value.

> line 111-113:

Is
```
if ($name -in $lookup.keys) {
    $value = ConvertTo-nbID -source $value -value $name
}
```
Should be
```
if ($name -in $lookup.keys) {
    $value = ConvertTo-nbID -source $lookup[$name] -value $value
}
```

This result in lookups on not existing urls.
