revlog: always use a Rust index for REVLOGv1 if rustext is present

We are about to change classes such as `rustext.AncestorsIterator` to
take a Rust index, hence we cannot have the option not to use the Rust
index.

Note: this can be refined depending on whether we want to keep this
option or not. We will have to make two versions of `AncestorsIterator`
and its sibling to support REVLOGV2 and CHANGELOGv2 anyway.

Meanwhile, this is the simplest change to make the tests pass.

=========================================
Testing single head enforcement: Case A-3
=========================================

A repository is set to only accept a single head per name (typically named
branch). However, obsolete changesets can make this enforcement more
complicated, because they can be kept visible by other changeset on other
branch.

This case is part of a series of tests checking this behavior.

Category A: Involving obsolescence
TestCase 3: Full superseding of a branch interleaved with another

.. old-state:
..
.. * 2 changesets on branch default
.. * 2 changesets on branch Z interleaved with the other
..
.. new-state:

.. * 2 changesets on branch Z at the same location
.. * 2 changesets on branch default superseding the other ones
..
.. expected-result:
..
.. * only one head detected
