[raudio] GetMusicTimePlayed() reports incorrect value after the stream is restarted for XM audio

[Peter0x44]

This issue can be reproduced on this example: https://www.raylib.com/examples/audio/loader.html?name=audio_module_playing
The progress bar does not reset upon pressing space, which stops and starts the stream.

This seems to be an issue exclusive to XM, as https://www.raylib.com/examples/audio/loader.html?name=audio_music_stream works correctly, and the progress bar resets when space is pressed.

This is a known issue, it requires some debugging...
