Don't show direction in notification timestamps

Currently all notifications except follow-related once include
and explicit direction text. (It missing in follow notifs is due to an
omission in 804ba0cdb6 which only added
the newly introduced with-direction to status-related notifs. Before,
presumably all notifs included direction text.)

But in the notification tray horizontal space is scarce
and notifs can already be assumed to only come from the past.
While it might not be too bad for the English localisation’s 4-letter
' ago' suffix, e.g. the Indonesian localisation’s ' yang lalu' needs
10 letters.

Thus instead of fixing the omission for follow-related notifs,
drop direction text from all notification timestamps.
