Adjust startercode branch to be in line with master

[apopiak]

People were having trouble compiling the startercode branch of the utxo-workshop here: paritytech/substrate#7256
Adjusted the branch to be in line with the master branch.

If you're bringing the video / workshop part of this up to speed, I highly recommend referencing a tag in the new videa rather than a branch like last time.

The reason is that when this PR gets merged the old video will talk about a branch that no longer points where it pointed when the video was recorded.

Well I was just trying to bring this branch to an equivalent state to master so that people would be able to compile it again and work from it.
I'm not planning on updating the video for now.
Would actually really appreciate if @nczhu could chime in on how to proceed :-)

Any updates on adjusting the branch to be in line with the master branch?
Thanks!
