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.

从报告中显示的 Repository.Commits 入口点开始，使用通过 git clone --depth xx 创建的仓库重现该故障。将浅层仓库的枚举结果与报告的 NotFoundException 进行比较，然后验证获取第一个 commit 时不会出现缺少对象错误并且能够成功完成。Issue 中未指定具体的测试文件。
