[Patch] Avoid to show conflict dialog with Replace Geometry

[GerdP]

What steps will reproduce the problem?

1. Open attached file
2. Search for type:way new | id:50896755 to select two ways with identical end points and direction
3. Use Replace Geometry

What is the expected result?

Nodes of existing way are replaced by those of the new way

What happens instead?

A popup dialog is shown which claims that I combine ways and I have to select Keep for each relation.
The texts in the dialog don't really reflect the intended Action.

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

I see no need to show this dialog.

Possible solution?

[Don-vip]

This doesn't feel the good place to add this logic. I'm sure there are other cases where we could skip the conflict, and we won't list all of them here. Better find something generic that can be called from utilsplugin2 ReplaceGeometry action.

I was also not very happy with the patch. Do you have an example for another situation where we could skip the conflict?
