conn: fix hostname move on connection reuse

When reusing a connection, the `host` and `conn_to_host` hostname
structs are moved from the template connection onto the existing one.

There was a NULLing of a tempplate member missing in `conn_to_host`
which could then lead to a double free.

Make this struct move into a static function, doing the correct
thing for both `struct hostname` in a connection.

Closes #18995
