Add is_reference relationships between synthetic case class symbols (#561)
* Add `is_reference` relationships between synthetic case class symbols Previously, doing "Find references" on a synthetic case class symbol (for example, named parameter of a `copy` method) then it only showed usages of that symbol and the non-synthetic symbol (for example, the case class field that matches the `copy` parameter). It didn't return usages of other synthetic symbols that also relate to the case class field (for example, the `apply` parameter). This PR fixes the issue by adding `is_reference` relationships between all synthetic symbols that relate to the same non-synthetic symbol. * Always upload SCIP to Sourcegraph Previously, it only ran `src code-intel upload` on git tags and master branch. * Add explicit JSR 305 dependency for Bazel build Needed to use `Nullable` annotation
