Uncatchable rejected promise

[jeffrson]

When the SFTP server disconnects during ("extended") connection handshake (requesting the sftp subsystem) the client application stops due to unhandled promise rejection. The promise in question is rejected in https://github.com/sanketbajoria/ssh2-promise/blob/master/src/sshConnection.ts#L80

I created a pull request that should fix the problem: #72 - it enables the application to catch the rejected promise, which was otherwise impossible.
