The task output of last execution attempt is lost for In-Error tasks

[fviale]

Steps to reproduce:

Execute the following workflow

<?xml version="1.0" encoding="UTF-8"?>
<job
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns="urn:proactive:jobdescriptor:3.10"
     xsi:schemaLocation="urn:proactive:jobdescriptor:3.10 http://www.activeeon.com/public_content/schemas/proactive/jobdescriptor/3.10/schedulerjob.xsd"
    name="script_groovy" 
    priority="normal"
    onTaskError="continueJobExecution"
     maxNumberOfExecution="2"
>

  <taskFlow>
    <task name="Groovy_Task"
    maxNumberOfExecution="3"
    
    onTaskError="suspendTask" >
      <description>
        <![CDATA[ The simplest task, ran by a groovy engine. ]]>
      </description>
      <selection>
        <script
         type="static" >
          <code language="groovy">
            <![CDATA[
selected = true
]]>
          </code>
        </script>
      </selection>
      <scriptExecutable>
        <script>
          <code language="groovy">
            <![CDATA[
println variables.get("test")
variables.put("test", "value")

throw new Exception("issue")
]]>
          </code>
        </script>
      </scriptExecutable>
    </task>
    <task name="Groovy_Task2">
      <description>
        <![CDATA[ The simplest task, ran by a groovy engine. ]]>
      </description>
      <depends>
        <task ref="Groovy_Task"/>
      </depends>
      <scriptExecutable>
        <script>
          <code language="groovy">
            <![CDATA[
println "uname -a".execute().text
]]>
          </code>
        </script>
      </scriptExecutable>
    </task>
  </taskFlow>
</job>

After all 3 attempts are executed, the task will be in In-Error state.

When trying to retrieve the output of this task, only two attempts will be displayed.
