Incorrect FSPIOP-Source header in a callback from switch to payerfsp - Invalid fulfillment from payeefsp case

[sri-miriyala]

In case, when the payeefsp (demomfi) is sending an invalid fulfillment, the switch is responding with an error callback to payerfsp (demowallet) only. In that response I noticed FSPIOP-Source header as "payeefsp" instead of "switch".

Expected Behavior:
When there is a failure in the switch regarding a transaction (partylook up, quoting, or a transfer) the FSPIOP-Source header should be "switch".
This is the case where payeefsp (demomfi) is responding (PUT) with an invalid fulfilment for a POST/transfer request.

Thanks Sri - the 'fspiop-source' header here needs to be the Switch as we discussed (as the error message originates in the Switch).. Thanks for log..

we need to raise a bug for this on mojaloop/project/issues as well to include in the normal backlog
