Oak-run offline reindex - async lane revert not taking place for stored index def after index import

During offline reindex using oak-run,
the index import phase first changes the async property to temp-async and keeps the original value in async-previous property.

This is reverted when the import is done. However it appears that the revert doesn't happen for the stored index definition and leaves that at
async = temp-async
async-previous = [async, nrt]

By setting "refresh=true", the stored index definition is copied to the regular index definition.
