[Toaster] [review-request] bbarrosp/terminology-fix

[Barros Pena, Belen]

It was brought to my attention that the description of Toaster we show on
first use was incorrect and misleading, aggravating an already bad problem
with confusing terminology.

This patch makes the suggested changes to the wording.
