fix: remove broken loading spinner (#67)

In this PR we remove the loading spinner that we have between page loads. It might seem like a good thing to have, but the `vv-loading` attribute in the version of Vegvisir this site is running is broken and only displays the spinner for a few frames regardless if the page has been loaded or not. We really need #66. When that finally happens, I will design a better loading screen anyways.
