conflict resolution broken for deleted objects via reverter plugin

[mkoniecz]

What steps will reproduce the problem?

1. Spot copyright violation added in changesets ​https://www.openstreetmap.org/changeset/72260628 and ​https://www.openstreetmap.org/changeset/72260619
2. Use reverter plugin to revert one of changesets
3. Run into 9k+ conflicts (as someone edited what was added in undiscussed import to remove invalid tags) - note that conflicts are between my version (deleted) and their version (edited), not deleted
4. Select all conflicts with ctrl+a, right click, select "resolve to my versions"
5. wait for conflicts to resolve (around one minute)
6. Try to upload changes

What is the expected result?

I will delete thousands of objects.

What happens instead?

Upload button is grayed out, in slightly older version I was able to press but I was getting message that there are no changes for upload.

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

Import was discussed in ​https://www.openstreetmap.org/changeset/72260608 and with DWG that confirmed that reverting it is OK.

First revert is in ​https://www.openstreetmap.org/changeset/75351558
