refs: don't loose info on resolve error

Typical use is git_reference_resolve(&ref, ref). Currently, if there is
an error, ref will point to NULL, causing the user to lose that
reference.

Always update resolved_ref instead of just on finding an OID ref,
storing the last valid reference in it.

This change helps simplify the code for allowing root commits.
