Listener Fuzzer: avoid dangling reference to dtor unique_ptr

[KBaichoo]

Let fuzzer own filter to avoid dangling reference if listener filter chain doesn't get created in connect.

We'd need to upgrade googletest in order to support moveable actions hence why I can't just move the filter into the lambda, but we have some build breakages associated with googletest, a windows patch.
