command: make audio switching persistent across file switches

mp_property_audio switched the audio stream, but didn't store the newly
requested audio ID to MPOpts.audio_id, which is used by --aid. This
meant that the audio track would be reset when advancing to a new file.

Change that to make it consistent with subtitle selection. (Whether this
behavior is a good idea or not is a different question - maybe it's not
a good idea, because tracks are essentially random, and this will
disable default selection of tracks.)
