fix(deps): roll back dependency @babel/core to v7.0.0-beta.49 (#285)

This Pull Request rolls back dependency `@babel/core` from `v7.0.0-beta.50` to `v7.0.0-beta.49`. This is necessary and important because `v7.0.0-beta.50` cannot be found in the npm registry - probably because of it being unpublished.
