Show toolbar and follow button for list visitor

[schu96]

Closes #9337

Fix

Technical

Remove if/else condition, uses the lst['key'] to determine if the user is the owner of the list and show relevant components within the account/view.html template.

Testing

• Create two user accounts and use one account to create a list of books
• Navigate to the list page and check that the follow button does not appear within the list of lists and single list webpages.
• Sign out of the list creator account and sign into the other newly created account.
• Navigate to the created book list, verify that the follow button appears on the list page and that pressing follow will add the creator's account to the visitor's Following tab.

Thanks @schu96! This is working well, but there are two things that are bothering me:

1. There are two sets of navigation breadcrumbs.
2. The databarView macro doesn't appear in the top-right corner of the view.

I've left some suggested code changes that will partially address number 2. In addition to those changes, you'll have to remove the breadcrumbs and the duplicate databarView, here.

So far, so good. The duplicate breadcrumbs and databarView are here, and should be removed.

Whoops, thanks for the reminder I had a complete airhead moment there
