Fix code search on local repos (#1204)

* Fix code search on local repos

We were making semantic queries with the full stringified repo ref.
Instead, we should have been constructing a semantic query using the
repository display name.

It seems that this was fixed coincidentally in #1190 via a condition
(which might now be possible to remove).

* Use indexed name in semantic query construction
