MINOR: mux-quic: perform app init in case of early shutdown

Adds a qcc_app_init() call in qcc_app_shutdown(). This is necessary if
shutdown is performed early, before any invokation of qcc_io_send().

Currently, this should never occur in practice. However, this will
become necessary with the new settings tune.quic.fe.stream.max-total.
Indeed, when using a very small value, app-ops layer may be closed early
in the connection lifetime.
