Rephrase infobar messages when not connected to Tor

- We shouldn't make a difference between "connected to Tor" and
  "connected to Tor daemon" as this probably doesn't make sense to most
  users. Also, both things are meant to occur simultaneously. See also
  #11290.
- Remove the second sentence as reconnecting automatically is what you
  expect from Onion Circuits and you also have no agency on this.
