TypeError: Cannot read property 'kind' of undefined in rxjsFinnishRule

Hey there, added the rules to a project using

TypeScript@2.6.2 TSLint@5.9.1

produced this stacktrace a couple of times:

TypeError: Cannot read property 'kind' of undefined

The process does not crash and completes showing lint failures concerning some files in the project as if nothing had gone wrong. I tried to get some info on the root nodes but a few console.logs haven’t yielded anything that would have helped to track down the source.

Should be fixed in 3.7.2.

Yep. Reproduced it in the fixtures. Thanks.
