Merging nodes: Always highest id chosen.

[skyper]

What steps will reproduce the problem?

1. select to existing nodes
2. merge nodes
3. undo
4. select in different order than last time
5. merge

What is the expected result?

Two different results considering the id of the resulting node

What happens instead?

Twice the same result. The higher id is used.

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

Need the same behaviour than connecting ways where different order in selection results in different ids.
