Example apps resetConnection crashes app

[NicoleYarroch]

Bug Report

If starting the sdlManager fails with an error, the example apps call the resetConnection method which attempts to stop the manager. This crashes the app.

This should be fixed in the Swift and the Obj-C example apps.

Reproduction Steps

1. Connect the example app to a TDK
2. Pull the cord before the app registers.

There was an error while starting up: Optional(Error Domain=com.sdl.lifecyclemanager.error Code=-2 "Could not find a connection" UserInfo={NSLocalizedRecoverySuggestion=Have you tried turning it off and on again?, NSLocalizedDescription=Could not find a connection, NSLocalizedFailureReason=The SDL library could not find a current connection to an SDL hardware device})

Expected Behavior

The app does not crash

Observed Behavior

The app crashes.
