- Remember if fuzzy was set or not for the open/close/all states.
- Use `fuzzy=false` for test, as `fuzzy=true` is the default (this is
the opposite of all the other values).
- Remove `ctx.Link` prefix for open/close states, this makes them
suspectible to the existing tests (the other filter links are also in
the format of simply having `?xx=xx&yy=yy`).
- Fix typo in test name.
