ServerPicker: Should always set selectedServers to array

[osbornm]

Currently when multi-Select is false selectedServers is set to an object not an array of one object. This is confusing.

We wont be fixing this until v2.0.0 because it is a potential breaking change. Here is a simple computed you can use to work around with issue along with a jsFiddle example

ko.pureComputed(function(){
  var result = self.selectedServers();
   if(Array.isArray(result))
     return result;
    else
      return [result]; 
});
