Dg 1637 Empty Filter for Persona without any policy

[PRATHAM2002-DS]

Change description

Preconditions:

• Create a Persona, add yourself in to users list.
• Do not create any policy or,
• Any existing persona that do not have any policy due to either never added any policy or deleted all existing policies

Steps:

• Go to Assets page, select Persona
• Go to Assets page, select Persona, go to Glossary page

Actual Result:

• On both Assets & Glossary page, no asset should be visible

Expected Result:

• All assets or GCTs are listed

Root Cause:

• When we create a Persona, we create ES alias without filters
• When deleted any policy in Persona, we simply reform ES alias filters & overrride

Solution:

• When creating a new Persona, we should create ES alias with filter in such a way that it does not return anything
• When deleting a policy, check if filters is empty, if yes add filter that it does not return anything
• We have simply used match_none for empty filters.
