Misleading error message to highlight "HostAlreadyClaimed"

When we encounter the HostAlreadyClaimed issue, the error message is pointing to the wrong route name.

OCP v4.12.z

Frequently

- Created three routes with the similar hosts, one without the path and other eith the paths defined.

# oc get routes
NAME     HOST/PORT                                                                       PATH    SERVICES        PORT   TERMINATION   WILDCARD
route1   httpd-example-path-based-routes.apps.firstcluster.lab.upshift.rdu2.redhat.com           httpd-example   web    edge          None
route2   httpd-example-path-based-routes.apps.firstcluster.lab.upshift.rdu2.redhat.com   /path   httpd-example   web    edge          None
route3   HostAlreadyClaimed                                                              /path   httpd-example   web    edge          None   <---------------


- Got 'HostAlreadyClaimed' error for the third route 'route3' which is expected because the path and the hostname of 'route2' & route3' are the same.

- In the route description, we could see that the first route that is 'route1' is reported to be the older route for the host but we expect it should report 'route2' because the hostname and paths are similar for the route2 and route3.

- However, deleting the 'route2' resolves the issue.

Error messages for 'HostAlreadyClainmed' issue should consider the route name to be reported on the basis of Hostname and paths.

Only hostname is taken into consideration where route's path should be checked as well and then the appropiate route name should be reported in the error.
