Angular architect test rule escaping its runfiles but not the sandbox

This is causing test failures if srcs are not copied to bin

As seen here https://github.com/aspect-build/bazel-examples/blob/a76be559cd89a645308ff0f2e6a02a82c780010f/angular/defs.bzl#L133 and here https://github.com/aspect-build/bazel-examples/blob/a76be559cd89a645308ff0f2e6a02a82c780010f/angular/defs.bzl#L195

Start by inspecting angular/defs.bzl at the linked lines 133 and 195, then reproduce the test failure when srcs are not copied to bin. Compare how the Angular architect test rule escapes runfiles with its behavior in the sandbox; done means the affected tests no longer fail in that configuration.
