chromeos: Update note-taking apps when ARC-enabled profile added.

Make NoteTakingHelper check new profiles' Play-Store-enabled
states when they're added. It appears that
OnArcPlayStoreEnabledChanged() is now not called in this
case, resulting in the list of Android note-taking apps
sometimes not being updated after login.
