Fix transient failure in TodoService spec

See merge request !9797

# Conflicts:
#	doc/api/v3_to_v4.md

For reasons unknown, the lack of `and_call_original` on this message
expectation was causing a transient failure depending on test order. We
narrowed it down using `rspec --bisect` to the following order:

API: Get list of jobs for a pipeline

`Kaminari.paginate_array` takes some options, most relevant of which is
a `total_count` parameter. Using the `commit_count` for `total_count`
lets us correctly treat the return of `Repository#commits` as a subset
of all the commits we may wish to list.

Addition of a new `Repository#commit_count_for_ref` method was
necessarry to allow the user to start from an arbitrary ref.

not leaked, leading to connection timeouts.
