Some Blinds do not stop when fully opened

[DaniEll-AT]

I am using the test-branch. There is one Venetian Blind that does not stop/turn of the relay when fully opened.

config:

cover:
  - platform: venetian_blinds
    name: "Blind-1"
    id: cover1
    open_action:
      - switch.turn_on: relay_1
    open_duration: 42900ms
    close_action:
      - switch.turn_on: relay_2
    close_duration: 43100ms
    tilt_duration: 1100ms
    stop_action:
      - switch.turn_off: relay_1
      - switch.turn_off: relay_2

It seems is_at_target_ does not return true, but I am not experienced enough in c++ to see whats wrong there.
I will have a look again later, maybe i can come up with a fix / pull request.

Further research has shown: This behaviour is only visible, when close-duration is longer than open-duration.
Most of the time this is a misconfiguration (it was in my case), but it has lead me to swapped open- / close-duration assignments in VenetianBlinds::control (@pawelma FYI)

Fixed with #9
