query with encoded_plan erroneously sets wrong plan in prepareds cache

execute the following sequence

prepare st1 from select * from `travel-sample`;
delete from system:prepareds where name = 'st1';
prepare sty from select * from `beer-sample`;

curl -v "http://localhost:8093/query/service" -H "Content-Type: application/json" -d '

{ "prepared": "st1","encoded_plan": "H4sI....."}

'

you get a 4080 back (encoded_plan parameter does not match encoded_plan for prepared statement).

do it again

curl -v "http://localhost:8093/query/service" -H "Content-Type: application/json" -d '

{ "prepared": "st1","encoded_plan": "H4sI..."}

'

you get rows from travel-sample, not beer-sample.

select * from system:prepareds;

"results": [
{
"prepareds":

{ "encoded_plan": "H4sIAAAJb..", "name": "st1", "statement": "prepare st1 from select * from `travel-sample`", "uses": 0 }

}
]

oops!
