Fix ui_devtools client address

Our dev tools used '0.0.0.0' as client address which doesn't work
on Windows. See some silimar discussion at
https://github.com/senecajs/seneca-transport/issues/37. Since we
don't have any remote server discovery in place, it would be
sufficient to use local host address '127.0.0.1' for showing the
local client address on chrome://inspect page. Thus this CL fixes
the client address by replacing with local host address.
