morph relation : renaming an object (#13404)

# Why
If we have a Morph Relation, like :
Opportunity <-> Company & People

Let's say it's a MANY_TO_ONE on Opportunity side

Then we have two joinColumnNames looking like
- ownerPersonId
- ownerCompanyId

Let's say someone renames the obejct Person (assume we can even though
standard obejcts cannot be renames per say at the moment in the API)

We need to update the joinColumnName and create the associated
migrations
