main/audiohook.c:  Fix bug in audiohook lead to out of sync MixMonitor.

MixMonitor out of sync due to the delayed rtp stream after SIP 183 with
SDP. In function ast_audiohook_write_frame, if other_factory_samples is
0, we never flush the factories although the result of
"our_factory_ms - other_factory_ms" may very large.
