[PROD] Remove 'Get Started' from all wallet states

[melyndav]

Steps to reproduce

1. Navigate to the CDapp.
2. Select the hamburger icon in the top right-hand corner.
3. From the dropdown menu, select 'Get Started'.
4. Note nothing happens since you're already on the CDapp landing page.

Expected behaviour

• The 'Get started' menu item should be removed from the dropdown menu, in the connected and not connected states across all responsive sizes.

Actual behaviour

• The 'Get started' menu item triggers from the hamburger menu on the landing page is no longer relevant with the latest landing page iterations.

Can we close this issue since it's been deployed to production @rdig @jakubcolony

This will be automatically closed by my #2448 which actually fixed this issue, but since that wasn't merged into master yet, this is still open

Once I merge it, it will automatically close this
