BUGFIX: Set up missing alias during nodeindex:indexnode

With this change running `nodeindex:indexnode`

- without `--postfix` uses existing aliases or creates a new postfix
  (like `nodeindex:build` does) and sets up aliases
- with `--postfix` given will use that postfix and not change aliases,
  as that's probably intended when passing the postfix manually

Fixes #370
