19104	Unglue node may remove way members from relations	GerdP	GerdP	"==== What steps will reproduce the problem?
1. load attached file
2. open the route relation in relation editor, note that the same node appears twice in the relation
3. select that node and press G to unglue
4. select ""Old node"" for tags, ""New node"" for the membership
5. refresh relation editor data

==== What is the expected result?
same way members in the relation, old node not in relation, new nodes in the relation
==== What happens instead?
one way member is removed, old node is still in the relation
==== Please provide any additional information below. Attach a screenshot if possible.
Probably a very theoretical error, just noticed it while looking at the code in `UnglueAction.updateMemberships()`
