Fix XCode warning after 'notifications-fuzzer' directory was removed

[michael-wb]

What, How & Why?

A bunch of old obsolete test files were removed as part of PR #7695, but an exclude entry for one of the items removed was still in the Package.swift xcode project file, which led to a warning when that file was opened in XCode. This PR removes that line that is no longer used to remove the warning.
