Strip timestamps from popup notification bubbles

Summary:
Fixes T11097. Currently, popup notifications show a useless timestamp with the current time, after D16041 made some things more consistent.

Strip these from the popup bubbles.

Test Plan:
  - Saw a popup bubble, no timestamp.
  - Viewed main notification list, saw timestamps.
