Initialize timeout remote address when channel was pooled, close AsyncHttpClient#1363

Motivation:

When channel was fetched from pool, we fail to initialize the remote
address, causing timeout exceptions to say «not-connected ».

Modification:

Properly initialize

Result:

No more erroneous « not-connected ».
