QE ignores filter while querying for stat queries

[Chinmay Zanpure]

Following Query JSON returns 21000 records whereas the limit is only 15:
{
 "table": "StatTable.NodeStatus.process_mem_cpu_usage",
 "start_time": 1469084760000000,
 "end_time": 1469127960000000,
 "select_fields": ["T=60", "COUNT(process_mem_cpu_usage)","process_mem_cpu_usage.module_id","process_mem_cpu_usage.inst_id", "SUM(process_mem_cpu_usage.mem_virt)", "MAX(process_mem_cpu_usage.mem_virt)",
"MIN(process_mem_cpu_usage.mem_virt)", "AVG(process_mem_cpu_usage.mem_virt)", "SUM(process_mem_cpu_usage.cpu_share)", "MAX(process_mem_cpu_usage.cpu_share)", "MIN(process_mem_cpu_usage.cpu_share)", "AVG(process_mem_cpu_usage.cpu_share)", "SUM(process_mem_cpu_usage.mem_res)", "MAX(process_mem_cpu_usage.mem_res)", "MIN(process_mem_cpu_usage.mem_res)", "AVG(process_mem_cpu_usage.mem_res)", "name", "CLASS(T=)"],
 "filter": [
  []
 ],
 "where": [
  [{
   "name": "name",
   "value": "",
   "op": 7
  }]
 ],
 "limit": 15,
 "sort": "asc",
