UICommand: reenabled after disableOnAjax when disabled on server side in request

Describe the bug

When a command button action willingly sets the disabled state of the button, the visual state of the button is still enabled. After another page update, this is reflected properly.

Reproducer

Please clone: https://github.com/stolp/primefaces-test/tree/PF-9038

Form:

<h:form id="frmTest">

 <p>It is expected, that the first button disables itself after its action, but it doesn't.</p>
 <p>The second button only refreshes the form to prove that the disabled setting is indeed present.</p>

 <p:commandButton disabled="#{testView.isDisabled()}"
   value="Button Action disables this button" action="#{testView.sleep()}" partialSubmit="true" update="@form" />

 <p:commandButton
   value="Button Action updates the page" action="#{testView.refresh()}" partialSubmit="true" update="@form" />
</h:form>

Expected behavior

The button state should be disabled after the action finishes.

No, that’s not needed, it is deprecated now.
