AnnotationSelectors are not properly serialized in GateXML

[sodre]

The gate.cloud.annotationselectors is not correct when serialized.

It should look like

<Feature>
  <Name className="java.lang.String">gate.cloud.annotationSelectors</Name>
  <Value className="java.lang.String">:Token,:Sentence</Value>
</Feature>

But instead it is looking like

<Feature>
  <Name className="java.lang.String">gate.cloud.annotationSelectors</Name>
  <Value className="gate.corpora.ObjectWrapper"><![CDATA[<?xml version='1.1'?><gate.corpora.ObjectWrapper><value class="list"><string>:Token</string></value></gate.corpora.ObjectWrapper>]]></Value>
</Feature>
