12162	"Unglue node of self intersecting way creates ""duplicated way node"""	malenki	team	"==== What steps will reproduce the problem?
1. have a way that contains a node twice (a self intersecting way connected with a node at the intersection is just fine)
(1.a: running validator gives a warning about a self intersecting way)
2. select the node at the intersection
3. press G
4. drag the way apart so it doesn't cross itself anymore

==== What is the expected result?

All data should be just fine and validator reporting zero errors.

==== What happens instead?

The validator now still warns about a self intersecting way
Additionally there is now ""duplicated way nodes"" error.

Btw: pressing ""G"" a dozen times generates a dozen nodes in the way.
