References div conflicts with --section-divs

[adunning]

With pandoc 1.15.0.6 and pandoc-citeproc 0.7.4, entitling the references section 'References' now results in a duplicated ID, and it is no longer structured as a section in HTML5:

pandoc -F pandoc-citeproc -t html5 --section-divs << EOT

---
references:
- id: test
...

# Test

@test

# References

EOT

Result:

<section id="test" class="level1">
<h1>Test</h1>
<p><span class="citation" data-cites="test">(n.d.)</span></p>
<div id="references" class="references">
<h1 id="references" class="unnumbered">References</h1>
<div id="ref-test">
<p>n.d.</p>
</div>
</div>
</section>

Result with pandoc-citeproc 0.7.3 (expected):

<section id="test" class="level1">
<h1>Test</h1>
<p><span class="citation" data-cites="test">(n.d.)</span></p>
</section>
<section id="references" class="level1 references unnumbered">
<h1>References</h1>
<div id="ref-test">
<p>n.d.</p>
</div>
</section>

One can get around the sectioning issue for now by adding a comment after the References heading, but the heading will not be marked as unnumbered:

---
references:
- id: test
...

# Test

@test

# References

<!-- This is the references section. -->

Result:

<section id="test" class="level1">
<h1>Test</h1>
<p><span class="citation" data-cites="test">(n.d.)</span></p>
</section>
<section id="references" class="level1">
<h1>References</h1>
<!-- This is the references section. -->
<div id="references" class="references">
<div id="ref-test">
<p>n.d.</p>
</div>
</div>
</section>

Similarly, the section appears if the position of the references div is specified, but it will not be given a class:

---
references:
- id: test
...

# Test

@test

# References

<div id="references"></div>

Result:

<section id="test" class="level1">
<h1>Test</h1>
<p><span class="citation" data-cites="test">(n.d.)</span></p>
</section>
<section id="references" class="level1">
<h1>References</h1>
<div id="references">
<div id="ref-test">
<p>n.d.</p>
</div>
</div>
</section>
