13591	[Patch] Change in multipolygon is not recognized by MultipolygonCache	GerdP	team	"==== What steps will reproduce the problem?
1. Load attached unglue.osm
2. Select the node where the inner and outer ring intersect
3. Press 'G' to unglue, a popup says ""Unglueing effected one relation"" (which is correct)
4. Select the node, keep left mouse button pressed and move the node a bit to the north
5. Select the rightmost way 
6. Select the unglued node, keep left mouse button pressed and move the node close to the other
one from step 4
7. Press ""M"" to merge the nodes and therefor close the outer ring.
8. Press ""Shift+V"" to run validator

==== What is the expected result?
no warning message
==== What happens instead?
Warning ""Multipolygon is not closed (1)""
==== Please provide any additional information below. Attach a screenshot if possible.
When I open the relation in the relation editor and change the order of the ways and save that the validator no longer complains. I think the problem here is that the MultipolygonCache is not updated when the nodes are merged in step 7.
I'll try to find a fix for this.
