test: use proper subclassing in `test-issue2137.t`.

To use changelog filtering on the repository, we plan to use "proxy" object that
perfectly mock a repository but with a filtered changelog.

Altering the `repo.commit` function using `extensions.wrapfunction` will prevent
the logic to propagate to the proxy class by the mean of inheritance.

We changes the extension to use subclassing as expectable.
