Fix record loss for certain certain feed type

1. Fix blindly replace connector between FeedCollector and
   AssignOperator.
2. Wrap AssignOperator into the FeedMetaOperator to make sure the
   operators inside (udf, accessor, etc.) can handle messages in the
   feed workflow.
3. Revise feed connection job merge function.
4. Test case fix.
