Fix a check-then-act race in `MemoizingEvaluator#getExistingValue`. If the node is rewound after the `isDone()` call, then `getValue()` will fail a preconditions check. `toValue()` is tolerant of this case, returning the latest value. This is important now that `SkyframeInputMetadataProvider` uses this method as of https://github.com/bazelbuild/bazel/commit/56fbf26284c119afeb9f4381afcdda83c085ab7d.

{Fast, Correct} - Choose two
Build and test software of any size, quickly and reliably.
Speed up your builds and tests: Bazel rebuilds only what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.
One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.
Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.
Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
