Review comment:
Is there a reason we aren't using the same project id that
SpannerOptions relies on
[ServiceOptions#getDefaultProjectId](https://googleapis.dev/java/google-cloud-clients/0.97.0-alpha/com/google/cloud/ServiceOptions.Builder.html#setProjectId-java.lang.String-)
if the value provider hasn't set it?
If you update this to handle my comment above, we will want to make sure we
keep the existing behavior of getting the default project id within the
execution environment and not when the pipeline is being constructed (unless
there is a strong reason for the swap).
