Empty JSEP in json causing validation error when jsep not required

[awsmsrc]

Our JSON encoder was sending an empty JSEP when subscribing to a stream

We have made our encoder smarter andnot included the empty key but I imagine people will have a generic janus Message type that has a jsep

There is no need to validate the jsep if it is not used

OR

document that you MUST not send it

cheers
