Error: ENOENT: no such file or directory, open '%PARENT_PATH%/metadata.json'

When I try to run Launch Kit backend, I get the following issue: Error: ENOENT: no such file or directory, open '%PARENT_PATH%/metadata.json' where %PARENT_PATH% is the folder above the one where Launch Kit is installed.

To reproduce:

1. git clone https://github.com/0xProject/0x-launch-kit-backend.git 0x-backend
2. cd 0x-backend
3. yarn
4. yarn start:js

I fixed locally by changing path.join(__dirname, '../../metadata.json'); to path.join(__dirname, '../metadata.json'); in js/config.js.

Thanks for the report. This is because we have our typescript under ts/src and javascript gets moved to js/ which a relative path would cause the failure.
