Title: HPCC-8138 Set ECL WU Description to blank using WUUpdate

In the existing code, calling WUUpdate with a Description of ""
will not blank out the description. That is because the existing
CClientRemoteTree::setProp() cannot set a property to be empty.
As a workaround, in this fix, I set the property value of ECL WU
Description to be NULL if a user sets it to be empty.
