RDKCOM-5526: RDKBDEV-3373 Fix tr69_12 - Verify GetParameterAttributes using empty string for top return 9002 (#14)

Reason for change:
CPE returns 9002 Fault response when ACS queries GetParameterAttributes
with empty string for top of hierarchy, which violates TR-069
specification. When using empty string for top of hierarchy, it
indicates the top of the name hierarchy.
Test Procedure:
1. connect to acs
2. ACS sends GetParameterAttributes RPC with empty string ParameterNames
(indicating top of hierarchy)
3. check if CPE returns GetParameterAttributesResponse 9002 error 

Risks: Low
