Double check this change in newgandi-type-lib.pl

I added setting up a connection here:

https://github.com/virtualmin/virtualmin-registrar/blob/master/newgandi-type-lib.pl#L787

As there was a call to $server, but $server was undefined, so it seems like it would always fail. I think, based on reading other functions and the definition of connect_newgandi_api, that this will fix that problem. But, I don't have this plugin setup, so can't test easily.
