23506	Pop-up notification for unsaved changes on deleting layer - no changes were made.	kathyaus	team	"==== What steps will reproduce the problem?
1. Upload OSM data layer after mapping from HOTOSM task.
2. Delete OSM data layer - layer deleted.
3. Attempt to delete boundary layer downloaded from HOTOSM tasking manager task.
4. Pop-up box appears 'Unsaved changes - Save/Upload before deleting?
5. Click on Delete now! button

==== What is the expected result?
The boundary is not changed when mapping a task - previously when deleting this layer there was no 'Unsaved changes' pop-up.

==== What happens instead?
Unsaved changes pop-up box appears - even when layer has no changes.[[Image()]]

==== Please provide any additional information below. Attach a screenshot if possible.
