Fixed comments for 68f1788b686b.

Also fixed:
- In ChooseMapActivity and SendFusionTablesActivity, check that the intent
inputs are valid.
- In ChooseMapAsyncTask, close the GDataParser in the finally block.
- In SendFusionTablesAsyncTask, check that a segment has more than 2
  points and that the segment stop time is set in prepareTrackSegment.
