Ignore notification from other users

This fixed the issue that both personal and work NAS try to suggest
adjustment to work notifications. And if the personal one wins, tapping
on smart actions in work notification will bring up personal app.

BUG: 110527159
Test: Send a message to work profile hangouts. Click on the smart action,
      work app is launched.
