Always prefer selection over current file

If you have selected some files, you intend to work on them. Also, this prompt
expects <kbd>c</kbd> / <kbd>s</kbd> which should cancel the next prompt in the
delete workflow. Rest of the three workflows are non-fatal.

Benefits of removing this option:
- code reduction
- one less step in the relevant workflows (more than one prompt feels dragged)

This prompt shows in the following workflows:
- delete: users have explicitly requested to prefer sel over current
- batch rename: key <kbd>^R</kbd> renames a single file
- archive: in most of the cases the user would want to archive the selection
- create sym/hard link: not a frequently used workflow (in general)
