RQG: Secondary indexing resulting in incorrect results for aggregate methods

./testrunner -i b/resources/dev-6-nodes-xdcr_n1ql_2i.ini -t rqg.test_rqg.RQGTests.test_rqg_concurrent_with_predefined_input,database=simple_table_db,reset_database=True,concurreny_count=1,index_quota_percent=40,use_mysql=False,replicas=0,input_rqg_path=/tmp/data_dump,populate_with_replay=True,reset_database=True,skip_cleanup=True,create_secondary_indexes=True,run_query_with_primary=True

Seeing broken results for the following cases when using secondary indexes.

Scenario :: run_query_without_index_hint
Reason :: mismatch in results :: expected [0:1]:: [505], actual [0:1]:: [251]

sql_query :: SELECT COUNT FROM simple_table WHERE NOT ((NOT (bool_field1) OR decimal_field1 = 5038))
n1ql_query :: SELECT COUNT FROM simple_table WHERE NOT ((NOT (bool_field1) OR decimal_field1 = 5038))
