Change view queryset from .all() to .none() (#3125)

- For some reason, the reverse URL lookups would fail for stock items which were not "in stock"
- e.g. detail pages for stock items would fail to render if the stock item was "destroyed" or "quarantined"
- changing the queryset to .none() fixed this
- I do not know why...
