No details when transfer is aborted

[Jani Monoses]

On the phone I am using an app scoped content store instantiated from QML.

When importing an item that already exists in the store, the transfer is aborted without any apparent information on what the item was. This makes sense since we already have the item, but for my use case - attachment to a message - it would help to know which item was attempted, so it can be taken from the existing store.
