Tapping on a timer notification takes you to the correct timer.

Bug: 29584816

Before if there were both missed timers and running/paused timers,
tapping on the running or paused timers would instead take you
to the same timer that tapping the missed timer would take you.
Now it will take you to the correct timer.
