This just saves some duplicate effort. There was no correctness issue in absence of this if condition. For e.g., when colstats is re-enabled, we are reusing this method and then we don't really need to redo the files partition, hence this if condition. In absence of this condition, HoodieMetadataPayload.createPartitionListRecord(partitions) would have been called everytime.

What is the purpose of the pull request
Fix HUDI-3782
Now that we have table configs for inflight and completed metadata partitions, and given that both reader and writer are going to rely on this config, we need to ensure that this config is updated properly even when any one of the metadata indexes is enabled/disabled.
For instance, let's say user started with metadata enabled and colstats enabed. Colstats partition was fully built and the table config got updated. Now, they disable it and we miss to update table config. So the writers won't update the colstats partition and it would be out of sync. Readers think that the table config has it so it's already in sync but that's incorrect. This patch fixes this issue.
Brief change log

Added a unti test which first writes with colstats enabled, then disabled (btu metadata enabled), and then re-enabled. Validated table config and metadata.
