Potential undefined behavior when calling Remote::list()
Details
When calling `Remote::list()` for a remote of a git repository, when that remote does not advertise any references, git2 passes a null pointer to the unsafe function `slice::from_raw_parts()`. Based on the safety section documentation of function, data must be non-null even for slices of length zero. Thus, the use of a null pointer leads to undefined behavior.
