NPE in Element when removing empty children
-------------------------------------------

                 Key: TAP5-675
                 URL: https://issues.apache.org/jira/browse/TAP5-675
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.1.0.4
            Reporter: Dan Adams


I have a page that renders an XML sitemap:

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"; 
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
        <t:loop source="items" value="item" t:mixins="domlistener">
        <url>
                <loc>${url.url}</loc>
                <lastmod><t:output value="url.lastModified" 
format="literal:yyyy-MM-dd" /></lastmod>
                <changefreq>${url.changeFrequency}</changefreq>
                <t:if 
test="showPriority"><priority>${url.priority}</priority></t:if>
        </url>
        </t:loop>
</urlset>

class:

void onEndElementFromLoop(Element el) {
        if (el.getChildren().isEmpty()) 
                el.remove(); /// NPE HERE
}

An NPE gets thrown at org.apache.tapestry5.dom.Node.remove(Node.java:186).

Appears to be the same issue or related to TAP5-640
