Do not render nav until we are finished loading

[allisonking]

Closes https://ethyca.atlassian.net/browse/PROD-1592

Description Of Changes

The ticket req was to make the management tab in the nav open by default. The reason why it was starting off closed was because, in general, we have the following accordion groups:

1. Overview
2. Data map
3. Privacy requests
4. Consent
5. Management

However, 4. Consent only shows up in plus environments. To figure out if we are in a plus environment, we have to query for it first. During the query time, the nav only sees 4 options, so it says "open 4 accordion tabs" and by the time the plus query says "yes we have plus, render Consent", only the first 4 tabs open up.

Relatedly, Michael also commented a while back:

Is there any way to delay showing everything until the page is fully ready? I think menu options for plus features pop in a bit later than the other items. I think it might look cleaner if we determine what to display, then once that determination is made, the fully formed nav is made visible.

So, to feed two birds with one scone, we now render a blank nav until the plus query is ready. This makes sure that the management tab will open up, and also that the plus only menu options don't pop in later 🐦🍰🐦

Pushed a minor nit, but otherwise LGTM and good idea 👍
