tests/performance: avoid check for toggle notification in "property-{get,set}"

Browse Source 
Bumping the reference count from 1 to 2 (and back) is more expensive,
due to the check for toggle notifications.

We have a performance test already that hits that code path. Avoid that
for he "property-{get,set}" tests, so we avoid the known overhead and
test more relevant parts.
