U/edgarivanv/fix false positives and not resolving nonindex files (#49)

Changed validations done to check if item was being unused.
- If an import in the form of `import 'foo'` is being executed.
- Added AsRef<str> implementation for `NapiLikeError` since newer
versions of rust enforce that for `Result::Error`.
- Added new version of `swc` that simplifies the dependency graph to
only use `swc_core` and `swc_ecmascript`.
- Fixed a problem with `resolve_ts_import` that marked import paths such
as `./Foo.base` as `ResourceImport` instead to the referred file
`./Foo.base.ts` which is a LocalProjectImport.
- Added `unused.js` to test the tool on client web, also, added the list
of entry points in client web.
