Gracefully handle rejected token Promise while creating real time subscription handshake link #708

Issue #, if available:

Description of changes: When using authentication type AWS_LAMBDA and providing the token as () => Promise<string> there is the possibility that the Promise is rejected. The Promise is awaited with the call await this._awsRealTimeHeaderBasedAuth outside of any try catch block. This lead to a "Unhandled rejected promise" exception. By moving the call into the existing try-catch block a rejected token Promise will be handled gracefully.
