17872	Faulty treatment of relation members when ways are split	osm@…	osm@…	"In the last 2-3 days, I came across the following behaviour leading to defective turn restrictions:

1. Given a turn restriction with ways A and B (as from/to) and node C (as via). 
2. One of the ways is split up so that the newly formed way D now connects to Node C.
3. Expected behaviour: JOSM should put the new way D into the relation, replacing the old from/to way, in order to keep the TR intact.
4. Actual behaviour: JOSM does not alter the relation, resulting in an error on upload (from/to not connected to via node). 

JOSM 15155, Java 11.0.3 / Kubuntu 19.04.
