Replace condition_exists w/ condition.present?

- #3497 introduces `<% condition ||= nil %>` on line 6.
- This refactor replaces the usage of `condition_exists` with `condition.present?`
- `app/views/org_admin/conditions/_container.html.erb` appears to be the only `app/views/org_admin/conditions/_form.html.erb` that passes the `locals : { condition` variable. The `<% condition ||= nil %>` code on line 6 should be sufficient for performing this check.
- Additionally, if `condition == nil` and `condition_exists == true` ever occurred, then we would encounter `NoMethodError` exceptions on lines 13 and 27.
