Bug in aggregateToCQL

[Michal-Leszczynski]

In the file recreate.go we can see:

var aggregatesTemplate = template.Must(template.New("aggregate").
	Funcs(map[string]interface{}{
		"stripFrozen": cqlHelpers.stripFrozen,
	}).
	Parse(`
CREATE AGGREGATE {{ .Keyspace }}.{{ .Name }}( 
    {{- range $arg, $i := .ArgumentTypes }}
    ...`

I believe that $arg and $i have mistakenly swapped positions.
We have encountered this issue in Scylla Manager with the following error:

await schema: get schema: cql keyspace traffickeyspace metadata: template: aggregate:4:11: executing "aggregate" at <ne $i 0>: error calling ne: incompatible types for comparison
