When a header that finalizes a chain of headers is succesfully imported
we also want to mark its ancestors as finalized.

There's no guarantee that the consensus digest item will be the last
one in a header, which is how it was previously being checked.

Thanks to Andre for pointing me to the Grandpa code that does this.

Fixes a problem with how the scheduled change was counted as well as
a SCALE encoding issue

* unpin nightly rust

* -specific toolchain + wasm
