      * Fix some comments and remove a pointless test
      
      * Code review feedback
      
      * 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.
