Skip Null List Elements When Mapping CAS Attributes To Authorities

Browse Source 
The io.spring.nullability plugin 0.0.16 upgrade tightens NullAway
analysis and flags list elements from the unannotated, raw
List<?> attribute value as possibly null. A null element has no
value to contribute to an authority, consistent with how a null
attribute value as a whole is already skipped.

See gh-19670
