Hour long trip is not segmented properly

[shankari]

Trip to karate and back was treated as one trip although karate lesson is an hour long.

Seems to be related to #97 - the trip to karate is not detected as complete.

And the trip from karate is detected as a new trip with a new start.

And we find its end

2016-03-01 02:08:59,936:INFO:Found trip end at 2016-02-29T17:03:53.396000-08:00

But the last place was at home

2016-03-01 02:08:59,949:DEBUG:last place doc = {u'enter_fmt_time': u'2016-02-29T08:47:50.

bjectId('56d4892c88f663446afb1397')}

So we say that all points from the last place are part of this trip. Normally, this would result in a straight line for part of the trip, but in this case, we actually did have points, so they were merged and we got the back and forth be part of the same trip.

It looks like the issue in which the phone stops collecting data at a point in which the server still doesn't see the trip is causing a bunch of issues.
