PR Summary

PSRP currently relies on XML for the transport messages. When using PSRP over SSH, if the target side fails, it sends back a text message. PSRP sees this and doesn't know what to do so it throws
a generic message which makes troubleshooting the issue more difficult. Change here is to throw
the text message which now looks like:

new-pssession : [test-machine] There is an error processing data from the background process. Error reported: Invalid argument '-np', did you mean:.

Previously:

new-pssession : [test-machine] There is an error processing data from the background process. Error reported: Cannot process an element with node type "Text". Only Element and EndElement node types are supported..

Since it's processing one line at a time, not able to get the whole message.
