Created Unassigned: Tweetinvi is not using the correct configuration settings when accessed from a Singleton object [2454]

The TweetinviSettingsAccessor accessor has 1 instance per thread. When TweetinviSettingsAccessor is a dependency of an SingleInstance class, this class cannot select which Accessor to use because there are multiple that could be available as 1 is generated for each children thread.

This could lead to have the TweetinviSettingsAccessor not to be the correct one used.
