Adding LSIF to private repos as a contributor is a confusing user experience

Users adding LSIF to their private repos get UI errors if they're not site admins. Although being a contributor is sufficient to set up and get precise code intelligence results, the current behaviour is confusing as Sourcegraph only shows settings and upload states if the user is a site admin.

Example: User is a repo contributor, sets up LSIF for their repo and get the following errors.

However, LSIF config is working and they get precise code intelligence results in their repo.
