[fix][test] AdvertisedListenersTest.setup

[congbobo184]

Fixes: #16544

Motivation

now in tests, we getFreePort not occupied, just written in configuration, so it may be created repeatedly. If the socket port is repeatedly, the test will become flaky.

Modifications

when we getFreePort, the port will be occupied and then if you use finished can release this port.
