PR cannot be found when --github-use-repo is specified.

Hello,

I have the following workflow (simplified):

core.workflow(
    name = "import-pr",
    authoring = …,
    origin = git.github_pr_origin(
        url = "git@github.com:thb-sb/myproject.git",
    ),
    mode = "CHANGE_REQUEST",
    transformations = […],
)

When I call copybara with this workflow, Copybara is able to find the revision for a given PR 1337:

$ bazel run @com_github_google_copybara//java/com/google/copybara -- migrate $PWD/my/copy.bara.sky -v import-pr 1337
Task: GitHub PR Origin: Resolving reference 1337
INFO: Executing GET repos/%s/pulls/%d
Task: Fetching Pull Request 1337 and branch 'main'

However, if I overwrite the url attribute of my import-pr workflow, it suddently fails to find the revision:

$ bazel run @com_github_google_copybara//java/com/google/copybara -- migrate $PWD/my/copy.bara.sky -v --github-use-repo git@github.com:thb-sb/myproject.git import-pr 1337
…
Task: Git Origin: Initializing local repo
ERROR: Cannot find reference(s): [1337, refs/tags/*

It seems that when --github-use-repo is used, Copybara doesn't GET repos/%s/pulls/%d. I think that way because the following logs aren't display when --github-use-repo is used, when they are without:

Task: GitHub PR Origin: Resolving reference 1337
INFO: Executing GET repos/%s/pulls/%d
Task: Fetching Pull Request 1337 and branch 'main'

Am I missing or misusing something here?

Yes, when an url is used it doesn't execute any of the GitHub path. I think it makes sense that it did for forks (or find another similar mechanism)
