HTML5 navtitle text is doubled when both navtitle and topic are keyrefs

See original GitHub issue

Expected Behavior

Navtitle text is output one time—for example, Topic.

Actual Behavior

Navtitle text is repeated—for example, TopicTopic.

Possible Solution

Not sure at this time.

Steps to Reproduce

Build the following ditamap:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE map PUBLIC "-//OASIS//DTD DITA Map//EN" "map.dtd">
<map>
    <title>Test</title>
    <topicref keyref="a" locktitle="yes">
        <topicmeta><navtitle><ph keyref="product-name"/></navtitle></topicmeta>
    </topicref>
    <keydef keys="a" href="a.dita"/>
    <keydef keys="product-name"><topicmeta><keywords><keyword>Topic</keyword></keywords></topicmeta></keydef>
</map>

Contents of a.dita don’t matter, but for example:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE concept PUBLIC "-//OASIS//DTD DITA Concept//EN" "concept.dtd">
<concept id="a">
    <title>Aardvarks are Awesome</title>
</concept>

         </ul>
      </nav>

Original issue seems to be cause by a bug in combining metadata during key processing.

See https://github.com/dita-ot/docs/pull/304 for an example of this workaround in use.
