rust-pyo3-index: _index_headrevs
This one demonstrates that why the `with_index_read` and similar
helpers are useful and was actually the main motivation for doing
them: if we kept the borrow used to grab the index before updating
the caches, there would be a panic when calling `borrow_mut`.
This was confirmed with an earlier version by the Python test.
There are perhaps some internal API clarifications to be made, as
the method updating the cache does a seemingly useless return), but
we are keeping it as it was in `hg-cpython`.
