fix(sharded): fix count in fetchSockets() method (#523)

MartinKolarik · web-flow · commit bd32763043a2 · 2024-02-19T09:11:00.000+01:00
If `fetchSockets()` is called shortly after the adapter was
initialized, the server count may still return 0, causing this to fail
with "timeout reached: only 0 responses received out of -1".
