Doesn't always pick up custom url from github-enterprise.uri

**Describe the bug**

I've been using this plugin with the GitHub Enterprise instance, that's why I have `github-enterprise.uri` set in my vscode configuration. I've occasionally been experiencing empty tiles in the GitHub Actions panels with a message like `No GitHub repositories found. Please open a folder that contains a GitHub repository.` even if I have a project with the GitHub pipelines open. However, I've been using some of the workflows in there before. If I'd toggle the `github-actions.use-enterprise` off and on all previously actions appear again. I assume the plugin doesn't correctly detect the active projects.

**To Reproduce**

Steps to reproduce the behavior:
1. Set both `github-enterprise.uri` and `github-actions.use-enterprise` parameters.
2. Authenticate as usual.
3. Open a project. Check the available GitHub Actions pipeline. All good.
4. Close all the tabs. Close the IDE.
5. Re-open the IDE (same project). Open the project. Check the available GitHub Actions. The list is empty.
6. Open any GitHub Actions workflow file by double-clicking. Check the available GitHub Actions tiles. The list is empty.
7. Go to setting and toggle the `github-actions.use-enterprise` parameter off and on. The list is now populated.

**Expected behavior**

The plugin should correctly detect the projects and the pipelines when both `github-enterprise.uri` and `github-actions.use-enterprise` are set.

まず、github-enterprise.uri と github-actions.use-enterprise を有効にして、報告された手順を再現します。VS Code を再起動した後、同じプロジェクトとワークフローを再度開き、その後設定を切り替えます。その手順に関係するプロジェクトとパイプラインの検出エントリーポイントを追跡します。設定を切り替えなくても GitHub Actions パネルに内容が表示され続ければ完了です。
