Typescript: item doesn't work for const imports

[alexhwoods]

import { A, B, C } from 'foo'

In the above example, you would expect chuck item bat to delete the const import B, but you get the error Couldn't find containing collectionItem

(if it's not clear, this is a low priority issue)

Also, compound ranges can work in this situation

chuck comma past bat

Fwiw this will be solved by #357, but that's a bigger change so it's possible we can do something to address this specific case in the meantime
