Subject: [PATCH] drop constraint before modifying the path (#2312)

Based on [this discussion](https://chat.openshift.io/developers/pl/6m4cojtiotdoueqot8uww5ybpe) we first remove the unique name index on the `iterations` and `areas` table before we modify the data.

This should fix the migration issue that was visible here: https://github.com/openshiftio/saas-openshiftio/pull/1082
