    Use a placeholder PagingSource to prevent running DataSource.Factory on main thread
   
    Paging3 introduced InitialPagedList which requires a PagingSource which
    was previous provided by synchronously calling PagingSourceFactory() on
    the main thread. This breaks the back-compat requirement from paging2's
    DataSource.Factory#create() to be called on fetchDispatcher, so instead
    of using a real PagingSource, we can simply substitute a placeholder
    PagingSource implementation which only ever loads empty pages and provides
    null keys.
