EDC discovery is returning wrong connector endpoints

[dhiren-singh-007]

API: GET : /api/administration/connectors/discovery Request : ["BPN"]

Current Behavior

EDC discovery api is returning the provider connector under provider BPN

Expected Behavior

EDC discovery api should return the Company connector and Managed connector under Host BPN For eg : Provider company "ABC" created the Managed connector for "XYZ" company with connector url https://connectorurl Now when we call the EDC discovery api it returns the response like below

{
 [
   "bpn":"ABC"
   "connectorEndpoint":
   [
   "https://connectorurl"
   ]
 ]
}

while response should be like

{
 [
   "bpn":"XYZ"
   "connectorEndpoint":
   [
   "https://connectorurl"
   ]
 ]
}

Assuming "ABC" and "XYZ" are the BPN of company

Steps To Reproduce

1. Create a managed connector for host company XYZ
2. Now call this api /api/administration/connectors/discovery with request ["XYZ"] , it will not return the newly connected connector
3. Now call this api again /api/administration/connectors/discovery with request ["ABC"] , it will return the newly connected connector under this BPN.
