Exception while trying to retrieve last commit from shallow repo

In my custom MSBuild task code tries to get last commit hash to put it into one of assembly attributes. Task works very well with repositories cloned with full depth but fails with the following error in repositories with limited depth created with command git clone --depth xx - where xx is number of last commits to clone.

/home/travis/build/DjvuNet/DjvuNet/DjvuNetBuild.Core.targets(20,5): error :
 LibGit2Sharp.NotFoundException: 
object not found - no match for id (d53e5a7166904479d42953bd0f91264f5ace1f6d)
[/home/travis/build/DjvuNet/DjvuNet/DjvuNet.NETStandard2.0/DjvuNet.NETStandard2.0.csproj] 

Code used to retrieve commit data is as follows:

    Repository repo = new Repository(RepoRoot);
    var commits = repo.Commits;
    var commit = commits.FirstOrDefault();

Seems to be libgit2sharp implementation bug as git fully supports enumeration of limited depth repos.

從報告中顯示的 Repository.Commits 入口點開始，使用透過 git clone --depth xx 建立的儲存庫重現此失敗。將淺層儲存庫的列舉結果與回報的 NotFoundException 進行比較，然後確認擷取第一個 commit 時能夠成功，且不會出現缺少物件的錯誤。Issue 中未指定特定的測試檔案。
