when writing instant file we should avoid directly write byte []

{code:java}
@Override
public void persistHistorySchemaStr(String instantTime, String historySchemaStr) {
cleanResidualFiles();
HoodieActiveTimeline timeline = getMetaClient().getActiveTimeline();
HoodieInstant hoodieInstant = metaClient.createNewInstant(HoodieInstant.State.REQUESTED, SCHEMA_COMMIT_ACTION, instantTime);
timeline.createNewInstant(hoodieInstant);
byte[] writeContent = getUTF8Bytes(historySchemaStr);
timeline.transitionRequestedToInflight(hoodieInstant, Option.empty());
timeline.saveAsComplete(false, metaClient.createNewInstant(
HoodieInstant.State.INFLIGHT, hoodieInstant.getAction(), hoodieInstant.requestedTime()), Option.of(HoodieInstantWriter.convertByteArrayToWriter(writeContent)));
LOG.info(String.format("persist history schema success on commit time: %s", instantTime));
} {code}
the saveAsComplete should not give writeContent which is a raw byte [].
