Subject: [PATCH] APIv4 - Fix access to case activities for administrators

Fixes dev/core#4769

Before: Case administrators with 'access deleted contacts' permission blocked from viewing Case activities in APIv4
After: Permissions work correctly.

The problem was the hook logic was incorrectly interpreting empty permissions to mean "no access"
when it actually means "unrestricted access".
