Resource set Search in admin UI is case sensitive

Bug description

When comparing the searching for Policy sets and Resource types there are inconsistencies in case sensitivity 

How to reproduce the issue

1. In the Admin console, under Authorization- Policy Sets search for default
2. The results will show hits for Default 
3. In the Admin console, under Authorization- Resource Sets search for resource
4. The results will only show results for resource, lower case. If you search for Resource you will get no results.

Expected behaviour

Case in-sensitive searches would be preferred 

Current behaviour

Searches for Resource sets are case sensitive 

Work around

None, search resources using both cases for the word

Code analysis

Policy Sets queries: _queryFilter:displayName eq "*default*" AND name eq "^(?!sunAMDelegationService$).*" 

Resource Types queries: _queryFilter:name co "resource" AND name eq "^(?!Delegation Service$).*"
