Table index is not getting modified on restarting the registry

[kuldeep-beehyv]

Hi team, We need to make a small change i.e. removing the Unique constraint on one column in an already existing table.
I have modified the schema JSON accordingly and restarted the vc-registry but this is not reflected in the database.
In the schema JSON, we removed the below part -
"uniqueIndexFields": [
"previousCertificateId"
],
and restarted the vc-registry.
