clone_and_chekcout_branch problem

[jdiego]

The clone_and_chekcout_branch.cpp inside the sample folder doesn't work on last version. I got the following error menssage:

Terminate called after throwing an instance of 'cppgit2::git_exception'
what(): reference 'refs/remotes/origin/awesome-cpp' not found

It's seem that a bug on temporary lifetime on GCC 10. I tested on GCC 9.2 and works. So, I will close this issue too. I'm sorry about this.
