In the New UI, the filters on either of the two portlets on the Staffing module does not work if a user attempts to filter for a value containing an ampersand. 

Steps to Reproduce:
1. Log into PPM and go to the New UI 
2. Go to the Staffing page 
3. In either the 'Resource/Investments' or 'Requests' portlets, enter a value containing an ampersand, but that does not begin with an ampersand (Example: R & S) 

Expected Results: Results are returned if there are any that include 'R & S' in the name. If no results, No results found. 
Actual Results: The following error is thrown and the list is not filtered: API-1006 : The value ''R' for Attribute 'queryString' is not in expected format or is invalid. 
Caused by DE39748
DE39748 is fixed on PPM 15.4.1.
