The `State: all-referrers-downloaded` is not always correctly updated downloading an area

[skyper]

What steps will reproduce the problem?

1. Have a way node outside the download area which has at least to parent ways
2. Move the node sightly
   • No warning about moving a node without all referrers downloaded outside the downloaded area
3. Download a small BBox around the node including its original position
4. Select the node and one of its parent ways and unglue

What is the expected result?

No warning about unknown referrers

What happens instead?

Unglue confirmation about other referrers not yet downloaded

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

The problem seems to be that the state for modified nodes is not properly set as the node indeed still has State: referrers-not-all-downloaded modified
