rust-revlog: add invalidation detection to `NodeTree` class

This will be useful for callers, such as `scmutil` who reuse a
`NodeTree` instance as a cache. They would otherwise get hard
errors if any mutation of the index occurred since instantiation.

This is something the C index does not provide.

Now narrow and shallow clone this and get a hopefully correct graph

To make updating the tests easier, we print the emitted nodes
sorted. This makes it easier to identify when the same node structure
has been emitted, just in a different order.
