Fixes #39 - Regression: Workflow Create Entity Task failure after migration

<b>Problem</b>: In latest versions, We are not supporting fieldname(valuetype) in "assigned to" field.

<b>Solution</b> : Add one more option in "Assigned to" field as 'Parent record owner'. Which indicates mapping

<b>Result:</b>
fieldname:assigned_user_id,
modulename:Contacts,
valuetype: **fieldname**,
value: **assigned_user_id**
