Et2Select + SearchMixin: Fix some bugs with display and selecting entries

- Fix clicking on text while editing triggered re-display
- Avoid unneeded node re-creation when editing free entry, handle empty value as removal
multiple=true:
- Fix clearing search removed previously selected remote results
- Fix adding a free entry did not move search down, covering the new value
multiple=false:
- Fix search & edit inputs were shown at the same time
- Fix edit free entry always took over making it impossible to search
