19939	[RFC] [Patch] Replace ParentRelationLoadingTask by DownloadReferrersTask	GerdP	team	"We have two very different classes which can download the parents of a relation:
- `DownloadReferrersTask` (used in Dialog for `Download parent ways/relations...` action and also in the `Download object...` action)
- `ParentRelationLoadingTask`(only used in relation editor for the `Reload`button in the parents tab, found no plugin that uses it

For the first one we have a unit test, and it is frequently used. The second one is probably rarely used. 
The patch implements the changes to replace the class and removes ParentRelationLoadingTask.
