Refresh of editableSchemaMetadata based on schemaMetadata

[kartikey-visa]

Describe the bug
On ingestion when schemaMetadata of a dataset is refreshed like removal of columns, the same doesn't get reflected in editableSchemaMetadata and the linkings to the removed columns still exist in editableSchemaMetadata

To Reproduce
Steps to reproduce the behaviour:

1. Attach glossary terms/business attributes to few columns of a dataset in datahub.
2. Now delete those columns from source and re-ingest the dataset in datahub.
3. Click on Related Entities tab of the glossary term which was attached to the now deleted column in dataset.
4. Find or scroll down to that particular dataset it will still show up in Related Entities tab.
5. Since the column to which glossary term was attached is now deleted, it should not show up in Related Entities, but it comes up in the list because the column along with its linkings (glossary terms etc.) still exists in editableSchemaMetadata

Expected behaviour
When the schemaMetadata of a dataset is updated (removal of columns), it should also update editableSchemaMetadata as part of its side effect.

Additional context
This problem is bound to occur in all the editable aspects of datahub.
