Infinispan Client doesn't pick up the hotrod-client.properties file

There is an existing test in Quarkus that was attempting to test that the hotrod client properties file was picked up at build time. But unfortunately the application.properties file also had the same setting set, so the test passes erroneously.

We need to fix the following line to no longer have the extraneous slash.
