Backport fix.


spanner IT fails for `deleteAllById_doesNothingOnEmptyIds` test with
error from Spanner: `INVALID_ARGUMENT: Failed to initialize transaction
due to invalid mutation key.`

**Trigger of this behavior change:**
spanner activated multiplexed sessions by default in
[googleapis/java-spanner#3996](googleapis/java-spanner#3996),
which triggers this error. When issuing a write() with a Mutation that
has an empty KeySet produces an exception in Multiplexed clients (see
[pr](googleapis/java-spanner#4023)), but does a
no-op in non-multiplexed ones. Unlike Regular session, multiplex session
needs a valid mutation to generate a precommit token.
