SDLCarWindow does not send video after reconnection when lock screen is disabled

Bug Report

SDLCarWindow does not send video data after reconnection when lock screen is disabled.

There is a bug in SDLLockScreenManager. SDLLockScreenManager sends SDLLockScreenManagerWillDismissLockScreenViewController notification even lock screen configuration is disabled configuration and does NOT send SDLLockScreenManagerDidDismissLockScreenViewController notification.
As a result, SDLCarWindow#lockScreenBeingDismissed remains true. This prevents the update of SDLCarWindow.

Reproduction Steps

1. Connect SDL iOS App with SDLCarWindow to SDL Core
2. Disconnect from SDL Core (lockScreenBeingDismissed becomes true)
3. Connect SDL iOS App to SDL Core again

Expected Behavior

Video data will be sent after step 3

Observed Behavior

Video data is not sent after step 3

OS & Version Information

• iOS Version: 11
• SDL iOS Version: v5.2.0
• Testing Against: Our internal SDL iOS app with our internal HU devboard

Test Case, Sample Code, and / or Example App

I will create PR later.
