Add navbar button back to main Building page from Comparison page

[solderq35]

If it's possible to link to a comparison page like https://dashboard.sustainability.oregonstate.edu/#/compare/%5B%2229%22%5D/2, then there should be an intuitive way to go back to the main building page. I think we said this feature was out of scope during the time comparison PR, but it is still a UI/UX issue that should be fixed eventually.
