Fix unit tests

- update string in CsvTrackWriter, CsvTrackWriterTest, and DescriptionGeneratorImplTest
- with Solo, UploadResultActivity can run by itself, but cannot run as
  part of the unit test. Modify the test to not use Solo.
- remove ANT+ tests in SensorManagerFactoryTest and replace them with
  bluetooth tests since most of the phones do not have ANT+.
- remove TrackDetailActivityTest since we are no longer using it to
  start the app. Will replace this with end-to-end smoke tests.
