For checkSessionId, there was a bug where it wasn't using the map syntax for setting the value.
Due to this, _checkDeletedSession wouldn't check if sessions were timedout.
In addition, posting offers after a connection was established would replace the connectionPair.
When the connectionPair is replaced, the code that checks for deleted sessions would no longer be checking the timedout session.
Resending offers occur if a PeerConnection goes into the disconnected state.
