Tsconfig Extends + Base Url + Paths Causing Lint Error on 4.7.1

Problem

Link to reproduction url with steps in readme: https://github.com/matthewwolfe/tsconfig-extends-bug

I have an application that utilizes multiple tsconfigs that extend base tsconfigs that are published as packages separately and available via node_modules. On version 4.7.0 this works perfectly, 4.7.1 introduces an issue where the paths in the base config are not resolved properly. In the repository provided, the main branch produces a lint error, the pinned-version branch does not produce a lint error.

Expected behavior

Tsconfigs with base url and paths that are extended should work consistently with tsc

Thanks for your report but your reproduction is not minimal and would require further debugging work that may not lead to a get-tsconfig bug. I provide Priority Support if you need assistance with this.

To make the reproduction minimal, can you make sure get-tsconfig and typescript are the only dependencies?

Alternatively, feel free to open a PR with a failing test like #59. This will probably be easier.

Happy to re-open once the bug is demonstrated to be in get-tsconfig.
