PG::DependentObjectsStillExist during start_sync on index drop+recreate

[annadowling]

When I execute start_sync I encounter the following error:

Starting sync failed: PG::DependentObjectsStillExist: ERROR: cannot drop index idx_spotlight_result_sets_default_on_tenant_template_created_at because index index_spotlight_result_sets_on_tenant_template_created_at requires it

Its not clear to me yet whether it was rolling back because of something else and this is a result of that.
Steps used to create this:

1. cleanup --group-name $groupName --everything
2. Manually clear all tables from target database
3. config_check --copy-schema  --group-name $groupName
4. bootstrap --copy-schema --group-name $groupName
5. start_sync --group-name $groupName
