mirror: remove "demo" module (#978) 

Summary:
This was used for ad hoc testing of the Mirror module before it was
integrated into SourceCred. We haven’t kept it up to date with schema
changes, and it is no longer needed: you can just run `sourcecred load`.

This was also the only untested code in the `graphql/` package, so it is
nice to remove it.

Test Plan:
Running `yarn test --full` passes.

// Command-line entry point for src/graphql/mirror.js, mostly for

// arbitrary root node. To use this module, first obtain the typename

// - sourcecred/example-github: id: MDEwOlJlcG9zaXRvcnkxMjMyNTUwMDY=

// Then, invoke this program, passing the name of a persistent database
// file, the typename and ID from above, and a TTL in seconds. The
// provided object and all its transitive dependencies will be updated
// if absent or older than the TTL, then printed in structured form.
