    Revert "daemon: Call goa_provider_initialize during start-up"
    
    Backend-specific initialization at startup was only used by the
    Telepathy provider, and is now unused.
    
    This reverts commits 692bdebf1c17b8506e3dedd356a835bc462522d6 and
    6d02cb7f3f536c9267b8e850a58815803f863502.
