title: TFS field set with rule is not saved in history
body: <p>I have created a rule for one work item type when its status is changed, to copy the current time from the clock and save it in custom field. The problem is that this change is not reflected in the item history, which I need.</p>
  
  <p>Any ideas?</p>
  
  <p>Here is the XML for the field at hand:</p>
  
  <pre><code> &lt;FIELD name="Date Closed (Scrum)" refname="Conchango.TeamSystem.Scrum.DateClosed" type="DateTime" reportable="dimension"&gt;
      &lt;HELPTEXT&gt;The date that the bug was closed&lt;/HELPTEXT&gt;
   &lt;/FIELD&gt;
  </code></pre>
  
  <p>and here is its Transition</p>
  
  <pre><code> &lt;TRANSITION from="Ready For Test" to="Done"&gt;
        &lt;REASONS&gt;
          &lt;DEFAULTREASON value="Work tested and completed" /&gt;
        &lt;/REASONS&gt;
        &lt;FIELDS&gt;
          &lt;FIELD refname="Conchango.TeamSystem.Scrum.DateClosed"&gt;
            &lt;COPY from="clock" /&gt;
          &lt;/FIELD&gt;
        &lt;/FIELDS&gt;
   &lt;/TRANSITION&gt;
  </code></pre>
