2820	NoMethodError uploading a deleted former relation member	anonymous	anonymous	"How to reproduce:
- Deleted a way which is a member of a relation
- JOSM prompts with dialog ""member of relation ###. Want to remove this way from the relation?""
- Answered with ""Yes, remove""
- tried to upload changes. (I've attached an OSM-file containing one such deleted way which fails to upload
