MINOR: resolvers: shut the warning when "default" resolvers is implicit

Browse Source 
Shut the connect() warning of resolvers_finalize_config() when the
configuration was not emitted manually.

This shuts the warning for the "default" resolvers which is created
automatically for the httpclient.

Must be backported in 2.6.
