14182	Cancel upload produces a mess :)	mrjones	team	"==== What steps will reproduce the problem?
1. Make changes
2. Click upload
3. Press cancel in the middle of the upload

==== What is the expected result?
Not to have uploaded anything to the OSM database.


==== What happens instead?
It uploaded half of the data (data up to the cancellation point) and when trying to upload again it shows a lot of conflicts.

==== Please provide any additional information below. Attach a screenshot if possible.
I am not sure if I am missing something when cancelling an upload. I am not familiar with the DB itself or the methods for updating it, but I would expect a rollback of the uploaded changes in case of cancel. And a commit otherwise..
