title: Dajngo all migrations are doubled
body: <p>I just started my django project and after running the migrations I was trying to create superuser. Then the error popped out that I have unapplied migrations (even though I just did it). When I checked the &quot;showmigrations&quot; it turned out that all the migrations are doubled. I have deleted migration file so does the db (because it was empty anyway). The problem has not disappeared. Does anyone know what may be the problem?</p>

  <p>In my venv for now I have django, graphene and graphene-django.</p>
  <p>This is the error:</p>
  <pre><code>CommandError: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0001_initial 2, 0002_logentry_remove_auto_add 2, 0003_logentry_add_action_flag_choices, 0003_logentry_add_action_flag_choices 2 in admin; 0001_initial, 0001_initial 2 in sessions; 0001_initial 2, 0002_alter_permission_name_max_length 2, 0003_alter_user_email_max_length 2, 0004_alter_user_username_opts 2, 0005_alter_user_last_login_null 2, 0006_require_contenttypes_0002 2, 0007_alter_validators_add_error_messages 2, 0008_alter_user_username_max_length 2, 0009_alter_user_last_name_max_length 2, 0010_alter_group_name_max_length 2, 0011_update_proxy_permissions 2, 0012_alter_user_first_name_max_length, 0012_alter_user_first_name_max_length 2 in auth; 0001_initial 2, 0002_remove_content_type_name, 0002_remove_content_type_name 2 in contenttypes).
  To fix them run 'python manage.py makemigrations --merge'
