Redirect to the dashboard after the tour

After the tour we should ground users by dropping them on the dashboard.

In the background, we delete the example text message template. This
means that users start from a clean slate when they go to add their own
templates

This also means some wording changes to the tour so it still makes
(some) sense:

- 1, 2 and 3 should refer to the current step, not describe the next
  one
- the link should take you to the dashboard
- change from ‘Get started’ to ‘Try this example’ because we’re using
  ‘Get started on the dashboard’
