Title: Fixing warnings in list_nsort when sorting by multiple fields.

When sorting a list by multiple numeric keys, many warnings are produced:

```
[% SET things = [
{
'foo' => 1,
'bar' => 1,
},
{
'foo' => 1,
'bar' => 2,
},
{
'foo' => 2,
'bar' => 1,
},
] %]

[% FOREACH thing IN things.nsort("foo", "bar") %]
[% thing.foo %] [% thing.bar %]
[% END %]
```
