ref(routes): Prioritize customer domains route (#70451)

In a936fb0 we introduced a new
withOrgPath prop to the Route component. This caused the route to have
the same behaviour as doing

```tsx
<Framgnet>
  {USING_CUSTOMER_DOMAIN && (
    <Route
      path="/some-path/"
      component={withDomainRequired(make(() => import('sentry/views/someView')))}
    />
  )}
  <Route
    path="/organizations/:orgId/some-path/"
    component={withDomainRedirect(make(() => import('sentry/views/someView')))}
  />
</Framgnet>
```

However the introduced logic generated the routes in the opposite order,
where the org slug version would get priority.

For some future changes this becomes important so I am bringing back
this matching behaviour
