SUID labels for source table in transformation diagram do not reflect SUID in transformation editor

The Transformation Editor changes to support new "default" Insert, Update and Delete resulted in the SUID letter labels not displaying proper state above the source table in transformation diagram.

Traced it to logic in TransformationHelper that was looking at "allowsUpdate(t-root)" and whether the UUID Sql string was NOT NULL.

The UUID Sql string is no longer used.

Need to change logic to look for:
1) allowsUpdate()
2) either (isUpdateSqlDefault() || update user SQL != null )
