2.59.1 re-introduced issue with transformation chains #5116
Description
The latest version 2.59.1 re-introduced the following issue:
Found multiple transformation chains that produce a variant of 'project [...]' with requested attributes:
we had in the past:
This time it seems related to test fixtures only.
Here is an complete output of the issue during the upgrade from 2.59 to 2.59.1: https://github.com/SimonMarquis/Android-Playground/actions/runs/21643770498/job/62390311349?pr=514

To honour the JVM settings for this build a single-use Daemon process will be forked. For more on this, please refer to https://docs.gradle.org/9.2.1/userguide/gradle_daemon.html#sec:disabling_the_daemon in the Gradle documentation.
Daemon will be stopped at the end of the build

* Try:
> Remove one or more registered transforms, or add additional attributes to them to ensure only a single valid transformation chain exists.
> Run the :artifactTransforms report to see the available artifact transforms.
> Transformation failures are explained in more detail at https://docs.gradle.org/9.2.1/userguide/variant_model.html#sub:transform-ambiguity.
> Review the variant matching algorithm at https://docs.gradle.org/9.2.1/userguide/variant_attributes.html#sec:abm_algorithm.
> Run with --info or --debug option to get more log output.
