call default_middleware_stack before merging stacks

Browse source 
`default_middleware_stack` seems to kick off the `on_load` calls that
may mutate the middleware stack.  We have to call that method before
merging middleware stacks, otherwise the middleware stacks get mutated
*after* the app middleware stack is built.
