fix: dev: Fix swapped arguments in redirect2() single-label branch

On a recursive resolver with nxdomain-redirect configured, an
NXDOMAIN result for a query whose qname is the root could corrupt
the view's nxdomain-redirect target, after which the redirect
feature stopped working for every subsequent query in that view
until named was restarted.

Closes #5908

Merge branch '5908-query-redirect2-name-copy-arg-swap' into 'main'
