Query - What's the behaviour when null is passed into this method?

RpcPriority.fromProto(null) will return RpcPriority.UNSPECIFIED. Added a unit test for this too.

SpannerActionOutcome outcome =
SpannerActionOutcome.newBuilder()
.setStatus(toProto(Status.OK))
.addDmlRowsModified(count)
.build();
sender.sendOutcome(outcome);
return sender.finishWithOK();
} catch (SpannerException e) {
return sender.finishWithError(toStatus(e));
} catch (Exception e) {
return sender.finishWithError(
toStatus(
SpannerExceptionFactory.newSpannerException(
ErrorCode.INVALID_ARGUMENT, "Unexpected error: " + e.getMessage())));
