You are getting this error since you deleted your remember_token column. When you login with
Auth::attempt($credential, false)
A remember token isn't saved. So the remember functionality should be disabled with the above line. However, the issue you are having is when you call Auth::logout(). It will attempt to replace the remember_token once you have logged out, but that column no longer exists. Replace the column in your database it should be working. You can test that the remember_token is NOT working by attempting to log in with the following:
if (Auth::viaRemember()) {
session()->flash('status', 'The user was authenticated using remeber token');
} else {
session()->flash('status', 'The user was NOT authenticated using remeber token');
}
