Fix implicit_header_references with duplicate headings.
Documentation says that when more than one heading has the same text,
an implicit reference `[Heading text][]` refers to the first one.
Previously pandoc linked to the last one instead. This patch
makes pandoc conform to the documented behavior.
See #8300.
