Terracer: Does not check for existing associatedStreet relation and silently deletes members

[skyper]

Hi

Thanks for your work so far !

I only have the option to create a new associatedStreet relation or not.

If their alredy exists a relation you get double relations.
If you do not create a relation, terracer silently deletes the members and does not add the buildings as members. It deletes information without message.

It would be nice if terracer would search for an already existing relation with the same name.

If the nodes are already member of a relation terracer should move the membership onto the building ways. That is the reason for blocker.

Thanks
