User mover fails migrating users with oauth_app_user_roles

[simon-contreras-deel]

After researching the case we have found the source of the problem.

In the import process we do:

• create_db
• create_org_oauth_app_user_roles
• ...
• grant_org_oauth_app_user_roles
• ...

In create_org_oauth_app_user_roles we have the following error:

ERROR:  role "carto_oauth_app_xxx" already exists

And in the grant_org_oauth_app_user_roles:

ERROR:  role "carto_oauth_app_xxx" does not exist

The reason is: in the role creation we are using a db connection to the source database instead of the destination one.

Thanks @owayss for the help
