Features in an XML file are not deployed when the file is placed in the deploy directory

Issue

JBoss Fuse supports the deployment of features by specifying them in an XML file, and dropping the XML file into the deploy directory. An example of such a file might be:

<features xmlns="http://karaf.apache.org/xmlns/features/v1.0.0">
 <feature name="soap-example">
  <bundle>wrap:mvn:org.fusesource.examples/soap/7.1.0.fuse-047</bundle>
 </feature>
</features>

This worked correctly in Fuse 6.0 and 6.1, but has no effect in Fuse 6.2.
