Remote command add_way does not close a way when the first and last node have same coordinates

[coso]

This command creates a way of four nodes, with tag building=yes, where the first and last nodes have the same coordinates:

​http://localhost:8111/add_way?way=45.437213,-2.810792;45.437988,-2.455983;45.224080,-2.455036;45.223302,-2.809845;45.437213,-2.810792&addtags=building=yes

If you run Validator it reports the warnings: "Area not closed" and 2 duplicate nodes (first and last).

Do all agree that the nodes should be merged in such cases?

[Don-vip]

Yep :-)

Then I commit :)
Merging to existing nodes is also done, but I am not sure the code is optimal. Fell free to improve it if needed.

In 5845/josm:

fix #8599: Remote control command add_way now creates closed ways correctly
Show old values and tooltips in add_tags dialog
All nodes added by add_node and add_way are merged with existing ones
