Fixes #6287: Remove V1 API entirely.

This commit removes the existence of the V1 API by moving some controllers
to pure V2 API controllers and removing other, unused API controllers
and their corresponding tests.
Fixes #7358/BZ1138411: correct empty org message logic on dashboard.

The dashboard was not displaying in the case of not having a default
org selected if you were admin.  This is because we wanted to prevent
showing the error message to admins in #4611 and because of spacing
being important in haml we ended up not showing anything at all. This
commit fixes the dashboard display in the case of an admin without any
default organizations.
