Request traversal after pause+no-resume

Once an activity is paused, if there was nothing to resume
afterwards, still trigger a traversal so that the syncengine
can refresh based on the no-longer-pausing state.

Bug: 392955356
Test: close a freeform task which doesn't report pausecomplete
Flag: EXEMPT bugfix
