Fix IntellijAspectTest to recognize both "//foo:bar" and "@//foo:bar" labels

Both mean the same thing in a monorepo, but only the latter is unambiguous, since the former could mean different things from different repos. Bazel will generate the latter for absolute labels in the main repo in a future release, and this change is forwards-compatible with that.

See bazelbuild/bazel#15916 for more information.
