IAE: Parameter 'member' must not be null

[gaben]

What steps will reproduce the problem?

1. After a long editing session I just split a highway which was part of a route relation

What is the expected result?

Way is split, no error.

What happens instead?

The way is split, but the error appears.

Please provide any additional information below. Attach a screenshot if possible.

I forgot to check the relation members if they are correctly placed in both the new and the old route.
