* Clarification comment in tests

* Some tests

* Reference counted `CandidateHash` in scraper

* Proper handling for Backed and Included candidates in scraper

Backed candidates which are not included should be kept for a
predetermined window of finalized blocks. E.g. if a candidate is backed
but not included in block 2, and the window size is 2, the same
candidate should be cleaned after block 4 is finalized.

Add reference counting for candidates in scraper. A candidate can be
added on multiple block heights so we have to make sure we don't clean
it prematurely from the scraper.

Add tests.

* Fixes "for loop over an `Option`" warnings (#6291)

Was seeing these warnings when running `cargo check --all`:

```
warning: for loop over an `Option`. This is more readably written as an `if let` statement
    --> node/core/approval-voting/src/lib.rs:1147:21
     |
1147 |             for activated in update.activated {
     |                              ^^^^^^^^^^^^^^^^
     |
     = note: `#[warn(for_loops_over_fallibles)]` on by default
help: to check pattern in a loop use `while let`
     |
1147 |             while let Some(activated) = update.activated {
     |             ~~~~~~~~~~~~~~~         ~~~
help: consider using `if let` to clear intent
     |
1147 |             if let Some(activated) = update.activated {
     |             ~~~~~~~~~~~~         ~~~
```

My guess is that `activated` used to be a SmallVec or similar, as is
`deactivated`. It was changed to an `Option`, the `for` still compiled (it's
technically correct, just weird), and the compiler didn't catch it until now.
