Inconsistent results executing prepared statements with star expressions in projection

When the encoded plan of a statement containing path.* expressions in the projection, is unmarshalled and then executed - wrong results ( missing fields in result entries ) can be observed.
 
Repro:
 
1. Setup 2 node cluster with Query, Index, Data service.
2. 

INSERT INTO default VALUES

(

"key::1", { "type": "document", "id": 1 }),

("key::2", { "type": "document", "id": 2 }),

("key::3", { "type": "document", "name": "Raj", "timezone": "Local", "id": 3 }

); 

 
3. 

prepare prep1 as select d.* from default as d ORDER BY id; 

 
4. Execute the prepared statement on both query nodes. On one query node the last document will have missing fields. This is incorrect.
 

[

    {

        "id": 1,

        "type": "document"

    },

    {

        "id": 2,

        "type": "document"

    },

    {

        "id": 3,

        "type": "document"

    }

] 

Issue:
 

• During the Marshalling of the plan, the number of star expressions is not preserved. And hence, the information is lost when the
  encoded plan is unmarshalled: https://github.com/couchbase/query/blob/master/plan/project.go#L101
• Hence, the projection order of each document is not re-evaluated for every projection item when there are star expressions in the
  projection.: https://github.com/couchbase/query/blob/d5fe10d0e024b8815ed61681c3db7e5a94012c64/execution/project_initial.go#L343
• Hence, only the top-level fields present in the first item processed by the InitialProject operator, will be be preserved for every item. Which is incorrect.
• This leads to fields being missing in the results.
