What steps will reproduce the problem?

2. Do something on one devices (rename track, delete, etc)

You will get duplicate files if you sync, disable sync, and sync again. When 
you sync the first time, the same track is on both the phone and on Google 
Drive. If you switch account or disable sync, then the mapping between your 
phone and Google Drive is removed. When you enable sync again, My Tracks will 
treat all the tracks on the phone and on Google Drive as new, thus you will get 
two copies.

If you can reproduce this, please document the precise steps so that we can 
reproduce the bug.
For now, going to close the bug.
