The data of the sponsor for whom the proxy is checking out does not appear correctly in the checkout user pane.
Steps to reproduce:
1. Go to the Check out app
2. Enter the number of user who is also a proxy for someone else
3. View the patron details that appear
Expected result: the info of the patron who was entered moves down, and the sponsor's info fills in above.
Actual result: the patron type of the sponsor is showing as the proxy's, not the sponsors. The number of open loans in the Proxy's as well. See attached
