fix(platform-server): wait for async app initializers to complete before removing server side styles (#16712)

Browse Source 
This fixes a flicker when transitioning from server rendered page to client rendered page in lazy loaded routes by waiting for the lazy loaded route to finish loading, assuming initialNavigation on the route is set to 'enabled'.

Fixes #15716
