Custom gateway dist is not picking up local index

[elliotBraem]

After merging #102, this broke the ability to run a custom gateway using a custom index.

Steps to reproduce:

1. use any version after alpha-21
2. use a custom dist and bos.config.json with index pointing to a local widget
3. see that alert shows, unable to be found

Downgrading to alpha-21 resolves the issue.

Acceptance Criteria

• [ ] local index widget is found when using custom dist
• [ ] test to verify
