`<choose>` fails to output fallback values if flushWith is set to an entity.

This test case demonstrates the problem:

<test-case name="">
    <input type="text/x-cg+xml">
        <cgxml:cgxml version="1.0">
            <cgxml:records>
                <cgxml:record id="1">
                    <cgxml:literal name="L" value="V" />
                </cgxml:record>
            </cgxml:records>
        </cgxml:cgxml>
    </input>

    <transformation type="text/x-metamorph+xml">
        <mm:metamorph version="1">
            <mm:rules>
                <mm:choose name="chosen" flushWith="entity|record">
                    <mm:data source="entity.data1" />
                    <mm:data source="L" />
                </mm:choose>
            </mm:rules>
        </mm:metamorph>
    </transformation>

    <result type="text/x-cg+xml">
        <cgxml:cgxml version="1.0">
            <cgxml:records>
                <cgxml:record id="1">
                    <cgxml:literal name="chosen" value="V"/>
                </cgxml:record>
            </cgxml:records>
        </cgxml:cgxml>
    </result>
</test-case>

The input record does not contain entity.data1. Hence, <choose> should fall back to the value of L. This only works, though, if flushWith does not contain an entity to flush on.
