Improve notification id

- _.uniqueId() is not sufficient since the ID is used to persist some data
  for notifications via session storage.  The id generated starts at a low
  number & increments w/o randomness.
- Using _.uniqueId() along with Date.now() adds a random value that cannot
  be replicated across sessions/refresh
