title: why remove-migration run my app?
body: <p>I did some version upgrade in last months and now I noticed that when I use "remove-migration" to delete migration that I reverted, it's first run my app.</p>
  
  <p>(I noticed that because we do update-database inside startup, so I got to situation where I can't remove migrations, since every time I tried remove migration - it automatically ran the startup which apply the migration to db, then it failed delete it, since it see it in db.)</p>
  
  <p>any idea?</p>
