Bug 1389844

Description of problem:
Bundle subsystem fails to parse bundle's deploy.xml if the rhq:archive task defines its exploded attribute with a value of "false" and has a child task of rhq:handover.

Version-Release number of selected component (if applicable):
3.3.7

How reproducible:
Always

Steps to Reproduce:
1. From the Bundles select _New_.
2. In step 1 of _Bundle Creation Wizard_ select _Recipe_ radio-button.
3. Paste the following recipe:
+
----
<?xml version="1.0"?>
<project name="helloworld-war-bundle" default="main" xmlns:rhq="antlib:org.rhq.bundle">
  <rhq:bundle name="helloworld-war-bundle" version="1.0" description="A sample bundle containing the jboss-helloworld.war from EAP 6 quickstarts">
    <rhq:deployment-unit name="helloworld-war" compliance="filesAndDirectories">
      <rhq:archive name="jboss-helloworld.war" exploded="false">
        <rhq:handover action="deployment">
          <rhq:handover-param name="runtimeName" value="jboss-helloworld" />
        </rhq:handover>
      </rhq:archive>
    </rhq:deployment-unit>
  </rhq:bundle>
  <target name="main" />
</project>
----
4. Select _Next_.

Actual results:
Bundle creation fails with the error "[1477690572690] java.lang.Exception:Failed to parse the bundle Ant script. -> org.apache.tools.ant.BuildException:Configure either handover or exploded" and the following is logged to server log

Expected results:
No failure and bundle creation continues.

Additional info:
From the documentation, it indicates that exploded must be set to false. However, it appears that if the attribute exploded is set, regardless of value, bundle creation fails.
