SELECT distinct name FROM <bucket> WHERE META(<bucket>).id IS NOT NULL gives 0 results with primary index using view.

1. Load bucket default with 2016 docs.

2. Execute test_meta using command:
./testrunner -i rqg.ini doc-per-day=1,primary_indx_type=GSI,standard_buckets=1 -t tuqquery.tuq.QueryTests.test_meta,GROUP=SCALAR;META;P0

The above test fails executing below query:
cbq> SELECT distinct name FROM default WHERE META(default).id IS NOT NULL;

"requestID": "0692d111-e365-4e53-bc2c-4cb4f038fcbf",

}

3.Below query works good:
cbq> SELECT distinct name FROM default WHERE META(default).`type` = "json";
