27089	Add the database alias to InconsistentMigrationHistory message	Alexander Holmbäck	Tim Graham	"In the file django/core/management/commands/makemigrations.py (line 97-100), an instance of MigrationLoader (loader) checks consistency on every database connection defined in settings.py.

{{{
for db in connections:
    connection = connection[db]
    if connection.settings_dict['ENGINE'] != 'django.db.backends.dummy':
        loader.check_consistent_history(connection)
}}}

The loader will then raise an InconsistentMigrationHistory exception for a connection whose migrations is not applied consistently, even if it's not to participate in the migration process.

I didn't expect `makemigrations` would check connections that isn't to be migrated. Also, the error message ""Migration xxx is applied before its dependency xxx"" (line 285 in db/migrations/loader.py) didn't indicate checked connection.

A more intuitive behavior would be to check only the connection that is to be migrated, or, if that isn't possible, include connection name in the error message."	Cleanup/optimization	assigned	Migrations	1.10	Normal				Accepted	1	0	0	0	0	0
