refs: make `git_reference_cmp` consider the nameethomson/reference_cmp
`git_reference_cmp` only considers the target of a reference, and
ignores the name. Meaning that a reference `foo` and reference `bar`
pointing to the same commit will compare equal.
Correct this, comparing the name _and_ target of a reference.
