fixes typescript named/imports for github/typescript

[stephenotalora]

The import/named rule from ESLint Core will report on lines that don't violate the rule when run on TypeScript files. We should probably do something similar to our no-shadow fix

Is there a rule called import/named in @typescript-eslint? I couldn't find it in the repository.

good catch, this only silences the error. it looks like we needed another plugin for the typescript parser to properly work with named imports. Extending from 'plugin:import/typescript' fixes this problem.
