    Fix checking if the user is a committer of the repo the PR originates from
    
    There are a few cases where if the PR originates from the same repo that it
    targets the ``project_from`` attribute of the ``PullRequest`` object is
    ``None``.
    Therefore, we need to check if the user is a committer of either the
    ``project_from`` if there is one and otherwise the target repo.
